Thread: Pro-Jection 2Di on Chevy V6

    Default Pro-Jection 2Di on Chevy V6

    Is their any way to make this operate correctly on a V6? Engine runs erratic at 2200 RPM, goes rich, than lean, then backfires. What am I missing?

    Yes, the EFI system must be tuned to the engine.
    Ensure the fuel pressure is correct (nominal 18 psi).
    Also, ensure the TPS voltage at idle is adjusted to .58 volts. (Early Pro-Jection 2D Manual) (Late Pro-Jection 2D Manual) (Holley Pro-Jection 4D, 4Di & 2Di Manual)
