hi guys been having trouble with me ba xr6t (manual ) not boosting all the time, have narrowed it down it is a lot worse when engine is up to temp or after I have been driving for a while. here is what I have done so far, been lucky to have another xr6t to swap some bits, have had turbo off tightened all studs bolts etc, replaced acuator cleaned and tried different solenoid swapped boost pressure switch replaced vaccum hoses swapped BOV changed plugs and regapped replaced fuel filter have had exhaust off had front bar off and checked hoses and intercooler and replaced clamps, have swapped engine crossoverpipe have had scanner on vehicle and found no trouble codes and no obvious problems watching live data. Im a mechanic by trade and getting frustrated I cant fix my own car so hopefully I have missed something obvious to some of you gurus out there any advise would be great cheers
