boost leak

[gregeternal2]

Where should I start looking? I've checked the charge pipe, blow off valve and most of the intercooler piping and haven't been able to pin point anything. Anyone have suggestions to what it might be? Thanks

Why do you suspect a boost leak?

Boost leak test is the best way.

Some boost leaks wont show until the system is pressurized v

You need to do a pressurized boost leak test to really find the leaks. This site has a great article describing how to test and they sell boost leak testers for a fair cost. I made my own because I wanted a little more functionality.
