ok, so, when i hit about 4-5K rpm, my car wont rev any higher, and my boost continues to rise. this is quite noticeable on the highway and wot. would this be the cause of a nasty exhuast leak; hence the "whistling/chirping" sound i hear when i accelerate for the first few rpms?


sorry if this didnt make sense, i just woke up.

 

check shaft play on yer turbo.

 

turbo was solid when i put it on less than 1K miles ago. and i havent really gotten on it on any of those miles out of fear of something else blowing up.

 

Have you checked for intercooler leaks? Mine used to always leak where my UICP attached to my intercooler. I suggest trying a leak test and seeing from there.

 

i agree on a boost leak check

 

I agree, cuz i had the same problem before and it came from the intercooler.
