    I wonder if the initial spray is to much which causes it to bog for a bit till it burns off? I'm gonna have to think about this a bit.

    I think your problem may be the map sensor. The sensor reads the air flow and tells the system how much fuel to spray to make the proper mixture. If not the sensor it's the mapping in the ecu as the curve for idle to 1/4 throttle is off. Also do you have a snorkel?

    I still think it's mass air flow sensor or ecu programming issue. The snorkel will also ad to the problem but the programmer should have taken care of the added air from the snorkel.

    It's worth a try but not sure if the ECU's will crossover.
