Alright here we go. I have a '03 GSR 133K mods ( they don't really count ) because I don't have any that truly make the car faster, i.e fuel pump more boost etc..

3" full buscher racing exhaust 3" front mount, injen piping and intake.

So this the story. I never really get on my car much it is a daily and well id like it to last a long time. I decided to go no the highway with one of my brothers and I did some pulls just to see how his Camaro did. I was in fourth gear on the pull and all of a sudden [bam] like a intercooler piping blew off but not as loud. Did it a few more times same thing. Scanned it and I got the P0234 turbocharger overboost, I looked at all the hoses and didn't see any disconnected. I run 1.5 bar of boost and it tappers off to like 1.2 bar at WOT - anyhow I was just curious where to look. it is 17 degree here in Michigan right now.

I had to replace my OEM Wastegate actuator. It went bad and the car started over boosting as a result. I would check into that. Also is it the factory boost control?

Cold weather will make you throw that code. Most people turn down there boost controller in the colder months. Due to the colder denser air.

Sounds like you hit fuel cut. The colder temps and the higher gears the higher the boost. I have thrown that code before. You should clear it and lower your boost just a little bit until it warms up. I also doubt your car would have done this in a lower gear. I make about 1 psi more in each gear as i go up. This is when boost by gear becomes nice to have.
