boost problem

[twisted952]

having a when i get to 20 lbs my truck is sputtering pretty bad. also just had the truck re flashed yesterday. i'm stumped cause there are no codes either. truck is running great until i hit the 20 lb boost point.

Loose I/C boot clamps or a cracked I/C boot would be the first thing to check.

you think the fuel filter might do this also

unplug the egr and try that.

how do you unplug it and if that works get the egr delete kit.

checked all of that. after i take the tune out the truck is pulling at 27 lbs of boost with no break up. my tuner is the diablo trinity.
