the problem: I can hold more the 5 psi.

Ive been working all after noon and last night on trying to find a boost leak. Anyway I was doing some search on here and I ran across a post that said remove the line to the wastegate... well when I do that I can boost as much as I push the throttle down. So its either the MBC or the wastegate. What are some good test to figure out which is the cause?

here is how I figured it out.

I connected a electric air pump to mbc and the boost gauge, I found it wouldnt let more than 5 psi through so I moved it to to 7 psi where I wanted it.


end of story.
