    GM Performance ECM Idle Issues

    It seems that no matter what I do to the idle it stays at 950rpms. what am I missing to lower the idle to 750? I tried copying some 5th Gen Camaro VE coefficient tables and even that didn't work. I just want to lower the idle to see if I can gain some brakes.
