Driving Coach Setup
The Driving Coach is a special feature designed to be your fuel economy dashboard and information center. It provides real-time visual and audio feedback about driving eciency and where energy is being lost. The driving coach will help you understand the optimal conditions for your particular vehicle through real-time observation, giving you the power to maximize your vehicle’s fuel economy.
Two hidden bonuses of driving more eciently are: saving money on fuel and helping the environment!
Before the Driving Coach can give you accurate information, it is important to make sure that the GT T+ is showing the correct speed. In the sections below, you will nd specic instructions for using the Driving Coach to become the best driver you can be.
40450 GT T
Set Economy Goal
This option will allow you to select a fuel economy goal. The Driving Coach will use the economy goal to calculate your driving grade.
It is very important to select an economy goal that is realistic for both your vehicle and the kind of driving you will be doing. If you will be driving mainly in the city or on the highway, choose a goal that is very close to the advertised fuel eciency for your vehicle in that type of environment. If you will be doing a mixture, choose an economy goal between the advertised city and highway mileage for your car.
Reset Average Economy
This option will clear the values stored in the GT T+ for the average fuel economy, the number of gallons used, and the grade in the Driving Coach.
Adjust Acceleration
This option will allow you to select the GT T+ sensitivity for the acceleration and deceleration in the Driving Coach; this aects the driving grade as­signed by the Driving Coach.

Driving Coach Setup (continued)
Checking Speedometer Accuracy
First: Change the Gauge Setup to have the Speed displayed on the main display screen. See page 8 for more information about changing the information displayed on the main display screen.
Next: Go to a safe place with little to no trac where you can perform a speed test. Make sure the speed limit is at least 60 mph. Here are two dierent ways to nd out your vehicle’s actual speed:
Method 1: GPS
1. Use a GPS device to compare your actual speed and the speed displayed on the Bully Dog.
2. Calculate the Percent Difference by using this formula:
Percent dierence =
Example 1: A GPS device reads 65 mph and the GT T+ reads 62 mph for one single moment.
GT T+ speed - GPS Speed
GPS Speed
40450 GT T

Step 1. Percent dierence =
Step 2. Percent dierence =
Step 3. Percent dierence = .046 or 4.6% then round up 5%
62 - 65
65
-3
65
Method 2: Stopwatch
1. Use a Stop Watch to measure how long it takes to travel one mile while traveling at 60 mph according to the GT T+.
Accelerate up to a speed of 60 mph (as shown on the GT T+) While traveling at that constant speed, record the amount of time in seconds that it takes to travel exactly one mile. *Use highway mile markers to ensure that your one mile measurement is correct.
2. Record the time.
3. Calculate the Percent Difference.
If it takes 60 seconds to travel one mile at 60 mph, then the GT T+ is accurately reading your vehicle speed.
If it takes 2 seconds more or less than 60 seconds to travel one mile, then use the formula to the right to calculate the Percent Dierence.
Once you have calculated the Percent Dierence, you can use that information to adjust the speed display as described below
To calculate the percent dierence use this formula:
Percent dierence =
Example 1: Using a stop watch the actual time it took to drive one mile while traveling at 60 mph according to the GT T+ was 63 seconds.
Step 1. Percent dierence =
Step 2. Percent dierence =
Step 3. Percent dierence =
Recorded Time - 60 seconds
60 seconds
63 - 60

60
.05 or 5.0%
Adjusting the Speed Display
1. Use one of the methods described in the previous section to determine the exact percentage dier­ence between the GT T+ and your actual speed.
2. Choose the opposite percentage in the Adjust Speed Display menu.
For example, if the dierence between your actual speed and the speed displayed on the GT T+ was 5%, you should choose -5% (negative ve percent).

Driving Coach Setup (continued)
Checking Average Fuel Economy
It is important to check the accuracy of the average economy readout on the GT T+ at least once every changing season. There are many reasons to check and adjust the average fuel economy, here is one example: The fuel delivered to gas stations during the winter contains an average of 1.3% less energy than the fuel delivered in warmer seasons. That means that the same amount of liquid is going into the tank, but it is 1.3% less eective, on average. There are many similar factors that aect your fuel eciency that you cannot control and the GT T+ cannot sense or adjust for. That is why it is important to adjust the fuel economy of the GT T+ every once in a while.
40450 GT T
To adjust the Average Fuel Economy displayed by the GT T+, follow these steps:
1. Go to the gas station and get a full tank of gas.
2. Reset both of the following gauges before driving away from the gas station:
- The Average Economy on your GT T+.
- The trip odometer on your vehicle.
4. Drive the vehicle for an entire tank (or two)
5. Calculate your vehicle’s average fuel economy by hand using the following equation:
• NOTE: If the speedometer on the vehicle is not accurate,
then the odometer will also be incorrect. You will need
to be able to calculate the exact number of miles driven
before your next refill.
6. Use the equation below to calculate the Percent Difference between the average fuel economy that you have calculated and the average fuel economy that is displayed by your GT T+.
Adjust the Average Fuel Economy
Follow the steps listed below to change the average fuel economy that is displayed by the GT T+:
1. Go to the Main Menu
2. Choose Vehicle Setup
3. Choose Adjust Economy Display
4. Use the buttons on the right to move up and down the percentages
5. Choose a percent value that is the opposite sign of the Percent Difference that you calculated using the equation above.
- For example, if you determine that the Percent Difference is 14%, you should choose -14%.

Diagnostics
This option reads the Diagnostic Trouble Codes (DTCs) from your vehicle engine. You can also erase these codes from here. To look up the DTC codes, the following website is very helpful: http://engine-codes.com/ You can also search for more information about DTC codes online using your favorite search engine.
IMPORTANT NOTE: Most DTCs indicate a problem with the engine, not with the tune or the tuner itself. If you want to know if a DTC is being caused by the GT T+ or not, uninstall the tune and drive your vehicle for about one week. If the DTC comes back, there is a problem with the vehicle and you should take it to a trusted mechanic. If the DTC doesn’t come back, reinstall the tune and test drive for another week – if the DTC comes back while the tune is reinstalled, contact technical support. Be sure to have your tuner, vehicle, and a computer with internet access available when contacting technical support. See page 65 for more information about contacting technical support.
Show Settings
The Show Settings screen will show you information about your vehicle, the GT T+, and your current vehicle settings. This screen will also indicate if the GT T+ tune is currently installed or not installed on a vehicle.
Uninstall GT T+
This option will allow you to uninstall the tune from your vehicle. This process is very similar to installing the tune, so be sure to take the same precautions listed on page 32-.
You can nd more information about uninstalling the download on pages 38-40.
Update GT T+ Software
This option will update the software on the GT T+ itself from the les on the Micro SD card. This is an important nal step to the update process. See pages 20-27 for more information about updating your GT T+.

UPDATING THE GT T+
FAQs about Updating
Why do I have to update my GT T+?
40450 GT T
OVERVIEW
Because it’s very important! These are just some of the reasons:
1. Vehicle manufacturers regularly change the part numbers and other information that the GT T+ needs to know in order to communicate eectively with your engine computer. If the GT T+ doesn’t have updated information, it may not work correctly with your vehicle. Bully Dog releases updates when necessary to keep up with any changes that vehicle manufacturers make and give our customers the best support possible.
2. Our technical support team gathers information about any problems experienced by customers and works with the engineers to x them as soon as possible. If these xes can help other people avoid similar problems, our engineers include them in the updates that we release for everybody. One of the most important troubleshooting steps we take when someone encounters a problem is to make sure they have the most recently released software version. This often immediately xes the problem!
3. Bully Dog engineers are constantly working to expand the features and vehicles that the GT T+ is able to support. Once a new vehicle or option is unlocked, they make sure it is available to everyone by including it in the updated software version.
Do I have to update my brand new GT T+?
Yes! There is no way to know how long your particular GT T+ may have been waiting on the shelf for you.
How often should I update?
Updates are released regularly, so you should check for them at least four times a year. A good rule of thumb is to check once every three months.
It is also a good idea to update the GT T+ if you have uninstalled the tune for any reason, like taking your vehicle in for service. This will help you avoid any problems during the reinstall if the engine computer has been flashed and has new part numbers (this is very common, even for a routine vehicle service).
What is included in updates?
+
Updated part numbers and other information from vehicle manufacturers, tested fixes for problems customers may encounter, and any additional features or vehicles that our engineers have unlocked.
How can I tell which software version I currently have?
1. Go to the Main Menu.
2. Choose the Show Settings option.
The software version is listed under System Info, next to Version.
How can I use the Update Agent to check for updates?
Start the Update Agent application and connect the Micro SD card to your computer using the card reader that came with your GT T+. If you have an older model of GT T+ and did not receive a card reader, you can purchase one online at www.bullydog.com. There are also many local retailers who carry card readers that are capable of supporting the Micro SD card format.
The Update Agent should automatically recognize the Bully Dog device, check the current software, and let you know if an update is available.
See page 26 if your SD card is not automatically recognized by the Update Agent.

PHYSICAL INSTALLATION
KEY CYCLES DISCLAIMER
IN ALL TOYOTA APPLICATIONS, IT IS VERY IMPORTANT THAT YOU DO NOT TURN THE KEY OFF AND ON UNLESS REQUESTED BY THE
GT. A KEY CYCLE IS WHEN YOU TURN THE KEY TO THE OFF POSITION, AND BACK TO THE RUN POSITION. IF AT ANY POINT THE GT STOPS, READ ALL THE INFORMATION ON THE SCREEN TO SEE IF IT IS SAFE TO CYCLE THE KEY. IF THE SCREEN DOES NOT SAY
TO CYCLE THE KEY, DO NOT CYCLE THE KEY, TRY TO START THE TRUCK, OR TURN THE KEY TO THE OFF POSITION UNTIL YOU HAVE
CALLED TECH SUPPORT.
40450 GT T
Be sure to check the list and description of included parts on pages 4-6.
Brief Preview
This is a quick list of the basic installation steps. You can find more specific information about each step in the next section.
1. Connect the OBDII adapter plug to the port under the dash.
2. Plug in the power cable to the fuse box and connect it to the adapter plug.
3. Run the HDMI cable under the dash.
4. Mount and connect the GT T+.
The illustration below shows how to install the power wire if there is no fuse box available inside the cab of the vehicle. If a fuse box is available inside the cab, there is no need to run the
power wire through the firewall into the engine bay.

PHYSICAL INSTALLATION
Detailed Instructions
1. Connect The OBDII Adapter Plug to the OBDII Port. See page 6 for a detailed description of the different parts of the OBDII adapter plug.
• Find the OBDII port in your vehicle. As shown in the
illustration, the specic location of the port can vary between dierent vehicles, but it is always somewhere under the driver’s side dash. The OBDII port will have the same shape as the end of the adapter plug.
• Once you have found the port, simply connect the adapter
plug to it.
2. Connect The Power Cable. The power cable is not really optional if you want to enjoy the originally designed functions of the GT T+. It is only optional under one of the following circumstances:
You do not want to keep the GT T+ permanently installed and plan on disconnecting it when you are not actively using the unit.
You want the GT T+ to remain on at all times, regardless of the eect that this could have on your car battery
You prefer physically switching the GT T+ on and o and do not want it to automatically power down when you turn the key to the o position.
OBDII Plug
Otherwise, in order for the GT T+ to work as originally designed, it is very important for the power cable to be installed as described below:
1. Locate an ignition fuse.
• An ignition fuse is one that is controlled by the position of the key.
• Sometimes we call this a “key-on” or “key-o” fuse.
• The fuse that controls the front windshield wiper is usually perfect, but any fuse that turns o when the key is turned o will work just ne.
• Every vehicle is dierent. There is no way to provide wiring diagrams for all vehicles. You will be able to nd the information for your vehicle
in the owner’s manual or online.
• Some vehicles have a fuse box inside the cab. If your vehicle does not have a fuse box inside the cab, you will need to locate the re wall and
connect the power cable to the fuse box under the hood.
2. Connect the power cable to the fuse.
• You may have received a fuse tap with your GT T+. See below for an illustration and instructions on using the fuse tap to install the power
cable.
• You can also simply put the power cable into the fuse
box along with the fuse that is normally installed in that location. See the diagram and picture for more information.
• If you did not receive a fuse tap, but prefer to use
one to install your power cable, you can purchase one at your local auto parts store. Be sure to ask for installation instructions if none are included with the fuse tap.
29
Using the Fuse Tap and Spade
1. Find and pull the fuse that you are going to use to insert the GT T+ Power Cable.
2. Slip the fuse tap over the prong on the fuse.
3. Fit the spade over the fuse tap and crimp them together with pliers.
4. Put the tapped fuse back into the fuse box.
PHYSICAL INSTALLATION
Detailed Instructions (Continued)
3. Run the HDMI cable under the dash.
This step helps you install the HDMI cable in a way that is discreet, stylish, and that helps to protect the GT T+
1. Plug one end of the HDMI cable into the port on the OBDII adapter plug.
2. Run the middle of the cable up through the dash on the driver’s side so that the end of the cable comes out near the A-pillar.
• It may be necessary to temporarily remove the weather stripping and dash panel to successfully hide the HDMI cable under the dash.
3. Make sure that there is enough slack in the cable to connect the GT T+ when it is in the mount.
4. Connect and Mount the GT T+
1. Install the mount that you have chosen. If you are using the Universal Windshield Mount included with the GT T+, see the installation instruc­tions in the next section.
2. Connect the HDMI cable to the GT T+.
3. Secure the GT T+ to the mount.
Using the Universal Windshield Mount
40450 GT T
+
IMPORTANT NOTE: Safety is your first and most important responsibility as a driver. Safety is also your first and most important concern when placing your GT
T+. Make sure the GT T+ does not create blind spots or distract the driver.
1. Locate the T-shaped socket on the back of the GT T+.
2. Place the square top of the Universal Windshield Mount into the square part of the T­shaped socket on the GT T+.
3. Slide to the left to secure the GT T+ to the mount.
4. Place the suction cup against the windshield and use the lever to secure the mount to the windshield.

INSTALLING THE TUNE
In order to enjoy additional horsepower and other advantages of tuning your vehicle, you need to use the Install Down­load feature. The process is basically the same when you are installing, changing settings, or returning to stock.
Important Preparation Steps
CAUTION! This option actively reprograms the engine computer in your vehicle – if the process is interrupted because of poor prepa-
ration you will have problems which could prevent you from using the GT T+ or even being able to drive your vehicle for a few days.
In order to have the best installation experience possible, it is important to review the instructions and pay close attention to the
preparation steps listed below:
40450 GT T
+
Choosing an Appropriate Time and Place to Install
Do NOT install if you will need to use the vehicle to get some­where soon.
DO set aside at least an hour for this part of installation. Under optimal circumstances the installation can be completed in less than 30 minutes. If you encounter any problems, you will need at least an hour to resolve the problem.
Do NOT install if the vehicle is in a remote location.
DO make sure that you have access to a phone, electrical outlet and a computer with internet access. DO update the GT T+ online by using the Update Agent before you try to install. You might need to connect to a computer to get special les from technical support if you encounter problems during the install.
Do NOT install if you do not have a way to contact technical support.
DO make sure that you can contact Bully Dog technical support. Technical support is open Monday-Friday, 8 a.m. – 5 p.m., Moun­tain Standard Time. If you decide to install on Friday evening and encounter problems, you might not be able to use your vehicle until you are able to contact technical support on Monday.
.. See page 43 for more information about contacting technical support.
Managing Other Electronics
DO turn o all factory installed electronics inside the vehicle. This includes:
Headlights, heater, air conditioning, stereo, DVD players, etc. Failing to turn o all electronics can prevent a successful download.
IMPORTANT NOTE: It is not recommended to use the GT T+ with any other electronic tuner designed to increase horsepower.
DO disconnect additional electrical appliances. Remove any chargers or electrical devices connected to:
Cigarette lighters, USB ports, or other types of electrical outlets in the vehicle
DO disconnect any other aftermarket electronic device. This includes:
Trailer brakes, stereo, alarm, CB, remote start, DPF delete, Sirius/XM satellite radio, etc.
Any electrical device that was installed after the vehicle was released from the factory.
Disconnect these items from the fuse box, or other power connection. You do not have to completely physically uninstall them; just make sure they are not getting power.
Make SURE all aftermarket fuses are removed Make SURE that the Battery is Charged
DO make sure that your batteries are fully charged before begin­ning any download.
It is a good idea to have a battery charger ready to connect to your vehicle if the batteries begin to lose their charge while you are installing the download.
Make SURE the Tuner is Ready
DO complete an online update with the Bully Dog Update Agent.
This is a free application available on the Bully Dog website.
This requires a computer with internet access.
See pages 20-27 for instructions on updating the GT T+.
KEY CYCLES DISCLAIMER

UNINSTALLING  RETURNING TO STOCK
What does this mean?
“Uninstalling the tune” and “returning to stock” are different ways to describe the same thing: writing the original (stock) information to the engine computer so it uses the settings that it used before you installed your GT T+. Doing this also sends a signal to the GT T+ to let it know that it is no longer installed on a vehicle, which will allow you to install the tune at a later time. The GT T+ will not allow you to install if the tune has already been installed on a vehicle.
When to Return to Stock
You should return to stock in ALL of the following situations:
• EVERY TIME you take your vehicle in for any type of service. It is a very common practice for the engine computer to be “ashed” (repro­grammed) during all types of service, even routine maintenance. If the tune from the GT T+ still installed when the engine computer is ashed, it can cause problems when you want to use your GT T+ in the future.
• If you want to install the GT T+ on a dierent vehicle. For instance
If you have a second vehicle and want to try the GT T+ on it. The GT T+ can only be used on one vehicle at a time.
If you want to let a friend try the GT T+.
If you have decided to sell the GT T+ to someone else.
• If the battery is having problems and could possibly go dead. Make sure to connect a battery charger while returning to stock to prevent
any complications that can be caused by interrupting the GT T+ while it is returning your vehicle to stock.
• If you need to disconnect the battery for any reason.

IMPORTANT NOTE: If you do not return your vehicle to stock, you may have to call in to technical support to have your GT T+ reset. There is a mandatory fee for this
service. See pages 42 and 43 for more information about the reset fee and contacting technical support.

How to Return to Stock
There are two ways to return your vehicle to stock.
IMPORTANT NOTE: Both methods are very similar to installing the tune to your vehicle, so you should make the same preparations and take the same precautions.
This means choosing a good time and place, making sure the battery is charged, pulling fuses (if necessary), disconnecting aftermarket electronics, etc.
IMPORTANT NOTE: There are certain times when disconnecting or interrupting power to the GT T+ can interfere with the engine computer programming process. If the engine write is interrupted, the programming on your engine computer can be corrupted. This can cause your vehicle not to start and possibly even require
the ECM to be replaced.
This illustration is an example of one of the times during the uninstallation when it is vital that the power is not interrupted and the tuner is not disconnected from the vehicle.
Note: There may be times when our technical support team will instruct you to disconnect the tuner even though the screen tells you not to unplug.
Uninstall Download
1. Choose the Uninstall Download option from the Main Menu.
2. Follow the instructions shown on the GT T+ screen.
3. When the GT T+ gives you a message that the tune has been removed, disconnect the GT T+ from your vehicle.
4. Check to make sure the tune has been removed from your vehicle.
5. Test your vehicle to make sure that it starts.
If this option is not listed on the Main Menu, use the option described on the next page.
Install Download > Return to Stock
1. Choose the Install Download option from the Main Menu.
2. Follow the instructions shown on the GT T+ screen.
3. Choose “Return to Stock” when the GT T+ gives you the option between “Change Settings” or “Return to Stock”.
4. Follow the instructions shown on the GT T+ screen.
5. Check to make sure the tune has been removed from your vehicle. See page 40 for instructions on how to do this.
6. Test your vehicle to make sure that it starts.

UNINSTALLING  RETURNING TO STOCK
What if I Don’t Return to Stock?
Here are some common examples:
• If you take your vehicle in for service, they will “ash” the engine computer. Even if you ask them not to, any dealer or shop will do this
automatically – it is standard procedure for any vehicle they see and they really can’t help themselves from following this ingrained habit. What they are doing is actually writing an updated le over any information that is currently saved in your engine computer. This includes the tune from your GT T+, so basically the tune is no longer installed and you will not be able to use the power level settings or any other options – but the GT T+ doesn’t know that, it still thinks that the tune is saved to your engine computer. Unless you go through the uninstall process with your GT T+, it will still show as installed and will not allow you reload the tune on your vehicle or on any other vehicle. The only way to resolve this problem is to contact technical support and have the GT T+ reset – there is a mandatory fee for this service. See page 42 for more information about the reset and fee.
• If you sell or trade-in your vehicle you will not be able to install your GT T+ on another one without calling technical support to have the
GT T+ reset. See page 42 for more information about the required fee for the reset service.
• If you sell the GT T+ to another person without uninstalling the tune from your vehicle rst, they will not be able to use it. You will prob­ably have negative consequences like an upset buyer, having to refund the purchase price or cover the cost of a reset, a negative review, and bad karma.
By now, you may have noticed a pattern: if you do not return your vehicle to stock and something happens to your engine computer, you
will need to call and pay the fee in order to have the GT T+ reset. Page 42 has more information about the reset process and the required fee.

How Do I Know if the GT T+ is (Still) Installed?
There are two ways to check if the tune is currently installed:
Main Screen
1. Look at the lower right corner of the main display screen.
2. If there is a box that reads “Power level setting not available until download is installed” the tune is not installed.
• If there is anything else in this part of the main screen, the tune is probably installed. You can double check by using the method described below.
Show Settings Screen
1. Go to the Main Menu.
2. Scroll down.
3. Choose Show Settings.
4. Check to see what the GT T+ shows next to “Download”.
5. If it shows:
• Installed – the tune is still loaded on the engine computer.
• Not Installed – the tune has been uninstalled and the vehicle is returned to stock.
• Recovery – there is a problem and you should contact technical support. See page 43 for more information.

MORE INFORMATION
Changing the Power Level
The power level tunes on the GT T+ gas are based on the octane of the fuel being run in the vehicle.
There are some times when this setting does need to be changed, like when lling the tank with a dierent octane than previously used before. Complete the following steps to change the power level tune setting:
1. Make the same preparations and take the same precautions as when you initially installed the tune. See pages 34-36 for more information.
2. Choose Install Download from the Main Menu.
3. Follow the onscreen instructions.
4. Choose Change Vehicle Settings when you are prompted to choose between that option and “Return to Stock”.
5. Continue following the onscreen instructions until the GT T+ indicates that the process is complete.
The illustration below is an example of one of the times during the installation when it is vital that the power is not interrupted and
IMPORTANT NOTE: This option actively reprograms the tune on your vehicle’s engine computer. There are certain times when disconnecting or interrupting power
to the GT T+ can interfere with the engine computer programming process. If the engine write is interrupted, the programming on your engine computer can be

Reset Fee
Why is This Policy in Place?
In the past, our technical support department has been ooded with people needing to reset their tun­ers. Because of this, we were not able to support the other people who needed help. The extra calls were coming for two dierent reasons:
1. Despite our best attempts to educate customers about the importance of uninstalling the tune before selling their vehicle or having it serviced, people did not remem­ber or did not take seriously the requirement of returning their vehicle to stock and were calling in repeatedly.
2. Some dishonest people were installing the tune on multiple vehicles and calling in to have the unit reset in between each tune. The tuners are designed to only be installed on one vehicle at a time.
Once the policy for the reset fee was created, the number of calls to request tuner resets was signicantly reduced and we were able to improve our support to everybody.
The reset process is relatively simple and a technician can help you complete the reset over the phone.

FAQS/TROUBLESHOOTING
My GT T+ Won’t Turn Off
Q. I have turned my vehicle off and removed the key – everything else has turned off. Why won’t my GT T+ turn off? A. The power switch on the OBDII adapter plug is in the “wrong” position. If you want the GT T+ to turn on and off along with
the rest of your vehicle, you will need to make sure that the power switch is in the “correct” position and that the power cable is installed correctly.
My Vehicle Won’t Start after I installed the Download
Q. My vehicle won’t start after I installed the download, what happened and how do I fix this? A. The GT T+ encountered a problem when it was writing to the engine computer. Follow these steps to resolve the problem:
1. Return the vehicle to stock. Test to see if the engine starts.
2. Update the GT T+.
3. Install the download again. Test to see if the engine starts.
4. Contact technical support if the problem persists.
My Vehicle Won’t Start after Returning to Stock
Q. My vehicle won’t start after I uninstalled the tune. How do I fix this? A. Follow these steps to get your truck running with the tune uninstalled:
1. Make sure that you have completed all of the preparation steps.
2. Go to the Main Menu on the GT T+.
3. Scroll down and choose the Show Settings Option.
4. Check what the GT T+ is showing next to Download.

45
10. If your vehicle still will not start, contact technical support.
My Vehicle isn’t Listed under Change Vehicle
Q. Why isn’t my vehicle included in the list under the Change Vehicle option? A. Chevrolet owners should choose the GMC option that matches the year of their vehicle. If your vehicle is very new or very old,
you may need to update (see page 20) or your vehicle may not be supported yet.
What Kind of Increased Performance Can I Expect?
Q. How much extra horsepower will my vehicle get? What can I expect for fuel efficiency improvements? A. See page 2 for information about additional horsepower. Many people do find that the increased horse power helps them get
the most mileage out of their fuel as possible. However, since fuel efficiency varies so much between different vehicles and drivers, there is no way to accurately predict fuel mileage increases. To get the best gas mileage possible, make sure to calibrate and use the Driving Coach to improve your driving habits. See pages 12-14 for more information about the Driving Coach.
