this is actually a question for my friends car. He has a 95 gs-t 5-speed that is stone stock except for a system, under glow, and boost and air/fuel guages.
so here is my question we installed the guages then went to put the mbc on and did all the hook ups after being educated by vfaq and thought we were good to go well no matter how far you turn the screw in on the mbc boost doesn't go up or down, other people have looked at the setup who have done the same thing say it is all hooked up right. We even went as far as to pull the hose off the waste gate actuator and no change in boost. I checked the turbo for shaft play and there was almost none at all. The car is in great condition and only has 80,000 miles on it. i dont think it is a boost leak, and even if it is wouldnt the boost change a little, most of the time the boost doesnt even get to 9lbs its more like 7-8. The stock bc is un hooked completely and we have also left it plugged in but with the vac lines off of it. I wondered if it is the waste gate so i moved it back and fourth and it moved freely could it be broken inside the turbo? the turbo still spools fine.
i have read alot of forums and found similar problems and i tried their solutions but obviously they did not work. this is a frusterating problem and would love to have some input.
