I noticed today that the car was sluggish... checked my boost gauge, and even with the whole RB turbo back exhaust, I've got a max of 6psi. It feels so goddam slow. I checked for vac lines and thought maybe the fuel cut was messed up, but it doesn't feel like a brick wall or anything. Just cuts off around 6 psi and holds there. Think this could be something else, or is it time for me to get the S5 turbo and manny? Thanks

 

Maybe your turbo is on its way out????

 

check your cats for clogs. in fact, check to see if they are glowing

 

damn you all... I didn't want to hear that the turbos going bad, and I've got no cats

 

Do a compression test and the ATF trick if you haven't.

 

If you have no cats, I would say the turbo. Good time to upgrade. Im trying to kill mine. HEHE. I boost 10psi on the stock turbo and It still won't give up.

 

Damaged wastgate or Boost leak loads of things?

What does it sound like ie does it sound like its trying hard or not?

No hissing or funny noises?

 

Do you hear a LOUD whooooshing noise when it does go into boost?&nbsp This is indicative of a loose clamp or hose on the intake...

once again reted wins. Seems like I blew the intercooler hose partly off, so I guess 6 psi was the limit, and after that it just leaked out. Clamped her down again and i'm back to ~9psi depending on gear. Thanks guys
