MAP or static referenced direct injection supply fuel system up to 800 rwhp with dual fuel pumps (recommended to run one pump full time, then activate secondary pump under load) with gasoline or race gas only (not E85). Supplies High Pressure Fuel Pump (HPFP) and port injection (and small wet nitrous) Includes in-tank supply system that retains OE transfer, fuel level sender, and EVAP functionality, upgraded feed and return lines, high capacity filtration and check valve, flow through t-block direct mounted on HPFP inlet tube, high capacity F1i regulator with provisions for both static and MAP reference.

Fuel system should not be used with E85 due to limitations with the OE fuel rails. (use L1E or L2 fuel systems instead)

Tuners are still working out the integration into the OE electrical system. Fore Innovations will provide detailed assistance on function of supplied components; however, we will not provide assistance with integration/tuning or elimination of alarm codes or the CEL.

1. Fuel pressure with static fuel pressure regulation must be set to 43 psi + maximum boost for proper injector spray pattern.
2. Manifold referenced fuel pressure configuration must not be subject to vacuum. (use boost only)
3. Use L1E or L2 fuel system to operate outside these parameters.

Ordered the cold air and tuner combo. Best tune I have had. Really woke up my 5.0
