2012 1500 that had a 6.2L swapped into it, with a camshaft that should have never existed. (Somebody thought they would experiment on this truck, a 220intake duration 244 exhaust, on a 116). It does sound mean as hell, but I can not keep it from stalling when coming to a stop. I have not worked with these newer PCMs yet. I have the truck running very well, fuel trims are great, but I do not see what I need to change for idle air flow, and dashpot functions, any help would be great. Thanks.
