Ok, my turbo is not working properly. The boost is not kicking in until about 5000rpms, in any gear, and is only reading about 3-4 psi. I checked the turbo and it spins freely and has no play. I was wondering if it could be a vaccum leak? This supra still has the origional wires on it. so I'm sure no one has ever changed or checked the vaccum lines. I'm giving it a proper tune up this weekend, if all the parts come. I guess I'll change out all the vaccum lines while I'm at it.
Any other suggestions?
