Sounds like you have a vacuum leak... Check all the vac lines, and especially the one on the front of the compressor housing that controls the wastegate actuator... Good luck...

Oh and you posted this in the wrong section... I'll let a mod know to move it... Look for it in the 2nd gen tech section...

 

got oil pressure to the turbo?

 

Boy it's a good thing the mods regularly check the reported posts...

 

belt loose?
