    Low speed throttle input issue

    2014 GMC 1500 6.2 SWAP
    TSP CAM. AND BOLT ONS.

    Truck runs good cranks and idles fine, makes great power. Has one issue when starting and making small throttle inputs in gear, the truck will die, starts back up fine but will repeatedly die from low throttle low speed maneuvers. If the truck gets some speed it wont die.
    any thoughts please
    I am attaching log and calibration.
    Please any advice would be greatly appreciated
    Thanks

    What is your idle speed? With my 2014 6.2 and 218/226 TSP cam. I had to have the idle speed and in gear idle speed above 760 atleast, closer to 800 the better. Or it would stall if I was trying to back into a parking spot or back a trailer.



    I can't open your file on my work computer.

    I have the idle set to 750 when warm. This truck will exibit this issue when starting cold before getting to operating temp and also when warm.

    Idle > Speed Control > Immediate and Proportional

    Sometimes these need to be made less sensitive with a cam
