what about the baro sensor? This will cause all the problems you are talking about.

with the stock tune the truck wouldnt run for crap either. and we got an underboost code and a baro code.

wait so even with the stock tune it acts weird? Im really confused...

yes the stock tune its messed up as well.

On my big tune no baro/boost codes and the baro code we were getting on stock tune was P2227 and that code is not shut off in my tune

i was thinking this before i got to the end of the thread. mine does the same thing on certain tunes. did you just replace the maf?
