    can you elaborate just a bit?
    What items do I adjust in the hand held?

    You're the man!
    Thanks. I will play around with this after work and report back.

    I would also adjust your PWM low mid and high flow all to 100.

    If that doesn’t solve it we will need to adjust the rate at which it returns to an idle. It’s factory set at 0 moving negative causes it to idle down quicker, moving it positive slows down the idle rate which will keep it from leaning out so much and attempting to die.

    I adjusted my pump rpm to right around my idle rpm.
    I adjusted my PWM low mid and high to 100.
    There has been no change. If anything it seem worse.
    I have played around with decel rpms before with no luck.

    I know this thread is old, but I had the same issue and had to take slack out of the secondaries linkage to get them to open at the same time/amount as the primaries. Since the TPS only reads the primaries they pretty much have to move identically or it will throw things off.

    Additionally I also set my PWM always on as mentioned, and disabled Decel Fuel Cutoff.

    Hopefully you haven't had to throw in the towel or had already fixed the issue. But if not, definitely check out the throttle linkage.
