First issue: I noticed the dumptube had some carbon deposits so I removed the wastegate. The gasket between the manifold and the wastegate was burned through on one side. It looks like there is a slight gap even when the wastegate is fully closed. Could I have put the [I forgot the name of the part ] in backwards during the install? I haven't had problems boosting. Or did I not tighten the wastegate down tight enough?

Second issue: I run the wastegate without a vaccum source. The reason being that when I got it dyno-tuned, it would only boost to like 4 or 5 psi. When disconnected it would go to the full 6.5/7 psi. Everybody was shaking there head like, "wtf?" So we left it disconnected and left it at that. I still to this day don't understand.....

What kind of a wastegate is it?? delta gate?? tial?

see updated sig

 

run without a gasket.

 

Your gasket was probably leaking the entire time, hence the lack of boost. Instead of your wastegate bleading off exhaust, your gasket was doing it
