.........but when the turbo comes on noting happens just a loud whisle type air noise behind the drivers seat. when stopped i opened the engine cover n when i rev it with the throttle cable there is a leaking air/rattle/dump valve type noise from the manifold/turbo area.
think its a air leak as when i was driving my boost gauge said 1psi an no more! could there b some soft of leak from that area??!!
