Missing at WOT on tunes......out of ideas
Ok a little background:
I just finished doing an EGR delete with a new oil cooler, 4 in straight pipe added the edge insight and SCT tuner and put in the Blue spring kit. while turbo was out we sent it in to get cleaned, the exhaust wheel was bad so I replaced it with a new power max. All filters and fluids were changed while the truck was down.
Stock program, tranny and tow hauls the truck runs great! Now when I put Eric's street tune, SCT street or performance the truck is missing above 3000 rpm when WOT. Fuel pressure is reading 68 at idle and drops to 60 stock and 52 tuned at WOT. We used a scanner to check injectors and all look good. The HPOP was putting out 3600 pounds in stock and 4200 tuned ( scanner showed it was looking for 4600 so a little low).
Also sure this is not related but when I run tunes the AC seems to kick out unless we are decelerating or stopped it won't work on a flat road at 55 with cruise on?
Have any of you seen this before? I don't want to keep replacing parts trying to figure it out.
thanks in advance
