Well since my chip was taken out because it crapped out, I have been running stock programming. I cant believe what a difference the IDM mod made compared to stock. I never ran the truck without a chip since I did the mod a while back but before the IDM mod I never saw more than 17PSI without my chip. I ran it hard up a good grade today and hit 22PSI WOT at 3000RPM. And this was at 8000ft. I never thought the results would be that good for stock programming.
