I have a 2004 F350 6.0 Diesel. Has an SCT with custom tuning, exhaust, EGT sensor and boost gauge. I get on the high way and I will punch it at 60 and it will take 9-11 sec just to hit 70. Feels like the truck is being held back. The boost gauge reads 25-30 psi and the smoke with the programmer that would normally blow out is about half as much as it would before. RPMs still jump up like they should when you punch it. I returned truck to stock and the there was no difference in power. No Check Engine Lights are on. What could it be? ICP, bad turbo, injectors? Any help would be greatly appreciated!:dunno:
