Im out of ideas (boost issues)
Alright im out of ideas here!!
I have done everything i can think of to get my turbo to boost to 10 psi and I just cant get it to happen.
Ive done LOTS of leak testing, and everything is pretty tight. There is a slight leak coming from two couplers due to busted worm gear clamps. Thats it as far as i have been able to tell. Ive got the wastegate completly sealed im 99% sure of that. Ive tested the wastegate with the vacuume sorce removed and it didnt change anything. Im out of ideas, SO if anyone has any suggestions please throw them my way. Im thinking about taking this to a near by performance shop and letting them diagnose/fix it.

if i had to guess i would say something is restricting your exhaust , is your maniford big enough? or is turbo to big for the d series engine?
thats all i can think of

& as far as boost leaks go.. u shoudln't have that tuff of a time eliminating them. & any leak is going to be progressivly worse, the more boost u try to build.. any leak is a horrible one!

So wait, you removed the vacuum hose to your wastegate, and you still couldnt build boost? if thats the case, something is clogging your intake, exhaust or you have a boost leak.
When my intake was clogged i couldnt boost past 3psi.
