hey i am still having the same problem that i was having before being that when i am in 2nd or higher gear at a low rpm and i go wot the boost shoots up to about 17 psi before it settles to 15 where i have my mbc set at. the rpms also briefly rise and then fall accordingly. when the turbo spools i also hear a loud whine it sounds almost like a supercharger, i read a post on nasioc and someone suggested it could be an up-pipe leak. i just took the car to the dealer and they took off the whole exaust including the up-pipe. before i take the up-pipe off again i wanted to know if anyone has had a sililar experience. thanks for the help
Uppipe leaks are a common thing. Well, most of the time. I'm getting ready to weld my headers and uppipe together (actually, I think Joey is going to do it, once I buy the headers from him) to completely eliminate that problem.
Mig welders are my friend. i had to change upipe gaskets twice a week, for a month, before i finally welded my header to gether. i tend to find ways to fix repetitive issues...such as valvetrain problems...shim under conversion..here i come!
