andy Iv seen some of your other posts and it seems like this shop is having a hard time If it was my truck Id get it out of there and find a good ford tech to fix it they maybe doing more damage than good just my 02 good luck

 

Your not kidding from a bad PCM to a bad HPOP diagnosis for the same problem in the course of a week. As someone else mentioned I think your being good buddied to death.

 

I have serious doubts about their diagnostic capabilities on a 6.0 myself. Even my cheap azz would have gone to a dealership by now for at LEAST an electronics diagnostic and reflash to rule that out and a HPOP system test to double check that the pump is weak and that it's not a system leak. Multiple PCM failures are simply unheard of and as far as the tuner causing them, my PCM has been flashed more times than I can count and I've never had a problem. I don't even go back to stock, I just change tunes.
