I Just installed an egr delete and new oil cooler on an early 04 6.0 now the engine ran excellent after the install three days later engine idles fine but running down the road it has no power. It sounds like the Turbo isn't spoiling up at all rpms are steady at 2500 WOT small amount of white smoke. Any ideas here guys anything I can check to confirm its the Turbo? I have ordered an AE scanner hasn't arrived yet any thoughts would be greatly appreciated. I also changed the icp sensor while I had the intake off.
