had 9.5psi now only 5psi were did it go??
 

d16y7 with teo4h with internal wastgate
i had a consistent 9.5 psi for first few days. then all of a sudden all i can get is 5psi. if i unhook the wastgate i get 7-8psi. i looked n looked for any leaks anywhere n cant find anything. the wastegate does close as far as i can tell. i am running the factory pcv setup. could this be where my problem lies? take it easy on me this is my first boost experience lol:confused:

It seems to me that there may be a leak in the diaphragm of the wastegate actuator thingy lol. Is this unheard of? I say that cause it is back to bout atleast 9.5 psi not hooked up but hooked up it goes up to 6psi then drops to 5 n stays there. Plz any help would be much appreciated. Thanx

Tested for leak. No leaks anywhere. Including diaphragm I'm thinkin of just making a home made controller

if the wastegate actuator diaphram was leaking you would get more boost. try adjusting the wastegate actuator rod.

I didn't know it was adjustable. I just tried unhooking it n turning it. But it didn't seem like it moved. N it still only hit 5psi. So I made a controller to put in the line from the turbo to the actuator. N the no psi when unhooked problem was a plugged exhaust. Was pieces of cat coming out the exhaust. Which is weird cause this car hasn't had a cat for yrs. Anyway I think I'm back on track the controller seems to work good so far.

yep. clogged exhaust will do that. glad you found the problem.

Thanx. I do appreciate ur help though.
