Jet Map

The horsepower gains listed above in the jep map are approximate gains. Depending on engine configuration and tuning, your gains may
be slightly different. The jet map is based on a nitrous system with a flowing fuel pressure of 6½ - 7 PSI. Any variations different than
6½ - 7 PSI will change your jet map and potentially damage your engine. We highly recommend using the Edelbrock Flow Test Tool

(P/N 76506) to set your flowing fuel pressure.

NOTE: When using the high horsepower settings with a direct port system, many variables come into play when setting proper timing

retard, such as timing with your previous horsepower settings, cylinder head configuration, compression ratio, tune-up, etc. We recom­mend consulting your engine builder to determine proper timing retard before using these settings.
