i will find out tomorrow

 

The exact same thing happened to my piping. That little plastic **** that holds the piping in place over the right side of the top of the engine snapped. The pipe jiggled but I did not lose boost at all. GM ordered the part and it came a week later. Installed, no problems anymore. Note that the "part" is the full piping from turbo to intercooler.

 

well the tech called me and told me that some bolts where loose i dont know where yet because i was with a customer so i kinda had to let him go so hopefully thats the problem

 

it was a bolt that came off on the wastegate actuator which left the wastegate open

 

I win!
Knew it had to bee the wastegate bleeding it all off.

 

good call that was one of my two guess's
