Congratulations on selecting the best performing and best backed automotive
supercharger available today... the VORTECH® V-2® Supercharger!
Before beginning this installation, please read through this entire instruction booklet and the
Street Supercharger System Owner's Manual which includes the Automotive Limited Warranties
Program and the Warranty Registration form.
Vortech supercharger systems are performance improving devices. In most cases, increases in
torque of 30-35% and horsepower of 35-45% can be expected with the boost levels specified by
Vortech Engineering. This product is intended for use on healthy, well maintained engines.
Installation on a worn-out or damaged engine is not recommended and may result in failure of the
engine as well as the supercharger. Vortech is not responsible for engine damage.
Installation on new vehicles will not harm or adversely affect the break-in period so long as factory
break-in procedures are followed.
For best performance and continued durability, please take note of the following key points:
1. Use only premium grade fuel 91 octane or higher (R+M/2).
2. The engine must have stock compression ratio.
3. If the engine has been modified in any way, check with Vortech prior to using this product.
4. Always listen for any sign of detonation (pinging) and discontinue hard use (no boost) until
problem is resolved.
5. Perform an oil and filter change upon completion of this installation and prior to test driving
your vehicle. Thereafter, always use a high grade SF rated engine oil or a high quality synthetic, and change the oil and filter every 3,000 miles or less. Never attempt to extend the
oil change interval beyond 3,000 miles, regardless of oil manufacturer's claims as potential
damage to the supercharger may result.
6. Before beginning installation, replace all spark plugs that are older than 1 year or 10,000
miles with original heat range plugs as specified by the manufacturer and reset timing to
factory specifications (follow the procedures indicated within the factory repair manual and/
or as indicated on the factory underhood emissions tag). Do not use platinum spark plugs
unless they are original equipment. Change spark plugs at least every 15,000 miles and

21. SUPERCHIPS NOTICE (APPLIES TO KITS SUPPLIED WITH SUPERCHIPS TUNER)
Regarding all GM vehicles with “ON-STAR” and Microtuner 2001. It has come to our
attention that GM vehicles equipped with “ON-STAR” communications may have trouble
being programmed with a Superchips Microtuner 2001. It appears the “ON-STAR” system
interrupts communications between the MT2001 unit and the vehicle’s PCM...” and after
cycling the ignition the vehicle can be started right back up.
Superchips is reviewing this and to temporarily correct for this situation, it is recommended that any vehicle to be programmed that has “ON-STAR” should follow these additional
steps FIRST.
1. Ensure the vehicle is off and keys are out of the ignition.
All model years up to 2002:
Locate “interior” fuse panel and remove QTY 2 SEO labeled fuses.
Locate “exterior” fuse panel and remove QTY 1 SEO labeled fuse.
NOTE: 2004 vehicles equipped with On-star that have aftermarket stereos will
experience problems withe the ability to re-program the vehicle’s ECM.
It is necessary to disconnect the aftermarket stereo from the factory
wiring harness before continuing with the programming procedure.
2003-2004 models years: Remove the “INFO, RADIO, RADIO AMP” fuse locat-
ed on the exterior fuse panel.
2. Follow the instructions that came with the Microtuner.
Once programming is completed, ensure the vehicle is off and the keys are out of the
ignition and install the fuses in the correct locations.
On GMC trucks, the interior fuse panel should be located to the left of the instrument
panel/dash board. If the panel faces the door, open the door to gain full access.
On GMC trucks, the exterior fuse panel should be located under the hood on the right
hand side of the vehicle. It will be labeled Fuse Panel or similar.
