Why does my Boost fall?

[Lrutts]

sounds like a boost leak test is needed. In my experience if you look at your car wrong you will get a boost leak

Haha i would agree, ok thanks guys. I had a feeling that it was one of those things, but i figured i should ask incase there was something i missed. I will go tighten things up and then go from there.

Whats the best way to test for a leak?
Just doing the whole block off both sides and use an air compressor?

What are the reasons that could cause my boost to hit 8psi then fall to 6 or 5 almost right away? I have an internal waste gate.
