This has me worried. I was on the road yesterday and decided to do a 2nd gear pull. Full throttle, then when the rpms hit 6k I got like a knock and it stopped pulling/engine light came on. Pulled over and saw nothing wrong. I tried doing another 2nd gear pull today and I feel a lack in power. Still under warranty

Has this happened to anyone before? what should I do??

 

What year?

How many miles on the plugs?

Have you done any mods recently?

 

if the engine chk light is still on, you shld get a readout on the error code.

 

2011 bone stock GSR
pulled a code P0234 turbo over boosting ?
don't have a boost gauge but I'm about to order one today:thumb up:
How do I fix this ?? Would I need a tune ?

 

That happened to me about a month ago. Take care of it asap. Mine blew

 

Any mods on the car? As you mentioned if you have warranty mind as well take to them.

 

no completely stock
yeah im pretty sure it's the wastegate

Damn that sucks

 

Have you verified that the FPR hose didn't pop off?

 

Are we sure it's not just cold out?

 

yeah first thing I checked

 

hahaha I was thinking this as well here in VA its getting really cold
I cleared the code and checking the wastegate when the temp goes up a lil
