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 recom-
mend consulting your engine builder to determine proper timing retard before using these settings.
