Working on an old C10 truck with a 5.3/prc heads/and comp cam. Don't have the cam specs at the moment. has a Boss hog stall in the 2400 range. I've lowered the Idle speed quite a bit to the 650 range and reduced the Throttle cracker airflow table and it helped reduced the truck trying to take off and cruise on its own. was cruising up to 20mph and shifting all the way up to into OD. Got it down to around 8mph but don't want to reduce the idle too much. Set all the transmission settings down to pretty much stock compared to what I normally do when tuning other vehicles. Wondering if my only other option is raising the Force Motor current table in the left side of the table would help reduce this. I can only lower the idle so much before getting into cam surge or truck sounding like its running poorly. Still on a base toon using SD only at the time before its lined out then back to a mix of MAP/MAF like stock. Wondering if trans builder cranked up the pressure internally in the trans when they built it and then theres no other way around this problem.
