Just took my car out for a quick cruise to see if she holds together. The spring that's in the 38mm external wastegate is only a 3 psi spring, so I made a homemade boost controller out of a home depot water line valve (the little one that hooks to your ice maker ) and put a T after that with a one way check valve so I don't get a vaccum leak due to my stupidity in putting the pressure line off the intake manifold :P The car stays nice and quiet until you start cranking up the boost...the vaccum from the manifold is sucking the wastegate open and it sounds like complete ----. Is there any other way I can keep it from doing that? I guess I could try ditching the check valve and dealing with a small vaccum leak if I had to, or should I just splice it into the line coming from the turbo itself?

God this sounds like a noob question...just transfered to 2nd shift and I'm so tired my brain feels like dust

That's what I "should've" done originally, but I wanted to use manifold pressure to help adjust it by. I pulled the check valve out and just put a restrictor in its place...the slight vaccum leak actually helped me out when I advanced my intake cam 2* so now it's got an awesome idle for a change. I've been fighting with the idle for the past 3 days now...it's ghetto, but it works :P
