    Stage Two Hesitation

    Guest-only advertisement. Register or Log In now!
    Under full throttle starting at around 2500 rpm, my car is sometimes spiking to around 21-22 psi. It then hesitates really bad like stuttering accompanied by slight banging noises, kinda feels like I'm hitting the fuel cut in a Honda, then brings the boost back under control and runs great all the way to red line. When it doesn't spike that high (19ish) it doesn't hesitate at all, runs perfect.

    The hesitation was once accompanied by a flashing check engine light I shut the car off and the light went out. Still off. I'll pull the codes tomorrow.

    GIAC 93 tune - and I'm running 93 gas

    Any ideas? I'm in stock setting now and the car runs great even at full throttle, any rpm.

    N75 valve?

    Cylinder 4 miss fires, sometimes cylinder 5. Looks like I'm doing plugs this weekend and moving some coil packs around.

    Look for a bad (bank 2) ICM as well.

    ICM - Ignition Control Module.

    Your car is hesitating because it wants you to go Stage 3.
    These are early symptoms of the turbo lady.
