This might be long so sorry. I got my DP F5 chip installed and took the truck out to test it. When I was in stock mode everything was fine. When I tested position 2 (60 Tow) the truck ran great but when I would slow down almost to a stop and push the clutch in the truck would die, not every time but a few times. On Pos 3 (80 economy) the truck would die almost every time I slowed down to stop and pushed in the clutch. I didn't test the other two Positions. I called and talked to Jody at DP, he was absolutely helpful and told me to check the IPR I pulled the IPR and disassembled it and cleaned it as the posted on PSN. I also pulled the ICP and cleaned it. and changed the oil and filter. The truck then ran fine for about a week until today, On Pos 3 (80 econ) I went to stop at an intersection and pushed in the clutch and the truck died. Luckily I could get it stopped without smacking the car in front of me. I'm worried to drive with the tunes on now don't want to rear-end someone. What should I check, is my ICP or IPR bad if so which one and how do I test them? Could it be anything else like my HPOP, I just recently pulled my HPOP and put all new o-rings in it. I'm getting ready for a 200 mile trip tomorrow so any help would be greatly appreciated.
