up-pipe leak?

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

gaskets

Did you use new gaskets? If you didn't you probably have a leak. I know it is a pain, but get new gaskets installed and torque them down good

It is only called speeding if you get caught!!

Welcome to my world!

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!

Depends on how much power you are pushing. Normally it shouldnt. We dont all have a WAGON POWAAA like fc735

It doesn't have anything to do with the power. It has to do with how they are made. The faces on the flanges aren't always completely parallel. That's where the leak comes from.
