i have a simple MBC (dawes devices hybrid mbc, appeads to be made from Ace Hardware parts) which was perfctly happy dialing in 17psi on my smaller turbo with this setup.
We have also been tightnening the wastegate actuator arm to try and help but the problem remains.
I suspect it has something to do with the restriction on the turbo inlet; we had to run the silicon 90 degree inlet hose between intake manifold runners in order to fit this damn thing in here. The runners are squeezing the silicon elbow and it does not look optimal.
Edited- now with photo. Also, it is squashed up against the rear passenger side intake manifold runnner, not between two of them:

It does not feel as though the hose is in any danger of collapsing, it is quite tough.... but i dont like the looks of it.
Is there a better way to mount this turbo and how? Any ideas? I also picked up an angled airbox setup from the junkyard in case thar ends up helping.
Thanks in advance!
