turbo codes thrown after flash

[Chevyboy2004]

hi folks i just flashed my 04.5 lly to a dsp 5 and used duramaxtuner nick's dsp 5 tune. the flash went great and the switch install was a breeze. i started the truck and checked it with the scan tool and i am getting the all the turbo codes in the book and at idle in any tune the truck is saying i have like 35 psi boost the desired boost is at 0 but the actual is at 35 psi. any ideas? thanks!

You are having some kind of logic issue. I would Flash back to stock and start over.
