I have a boost leak can't figure out where it is, recently upgraded to a fmic, only leaking at 15-20 psi or higher, don't have a boost leak tester, does someone I can borrow I'm located in Monticello.
did you take the rubber end caps off of your TB hose? This thread on 3Gwrx.com has a lot of info on it. Might be worth checking out the pictures and posts and double checking your engine.
Sorry that was not the thread I was thinking of... similar info. Here is the NASIOC thread with the same title ... it has better info. INTERWEB LINK THING
Go get yourself a PVC cap, drill a hole in the end, and add a valve stem. If it is a hair too small, wrap tape around the end until it's the right size. Don't forget to disconnect any crankcase ventilation lines that may pressurize the block. Blowing out your cam/crank seals is not desirable. After you have this fancy device, mix up some soapy water and go to town.
