hey guys I've been tryin to resolve this issue for a few weeks now, but today I've finally cracked it lol problem is that my car will not boost over 5-6 psi ... this is ridiculous feels like a camry could pull past me without any problems >.< in saying that I hope u guys understand the frustration I'm going through lol
anyways the car is a Nissan Skyline R33 Series II, has got turbo back exhaust, k&n panel filter, stock intercooler and gizmo ms2 boost controller/turbo timer, surely there must be somethin wrong right? ... my boost controller seems to have no effect whatsoever at any setting, would this be because I have not wired up my boost cut defender lines? in the diagram it looks like it goes to the ecu but I havnt been able to get my hands on any wiring diagrams, at first I thought it may have been that it was caused by me just removing the factory boost solenoid completely and leaving the harness just sitting there but after putting it back in I still have no difference, the car does hold the 6psi fine, it doesnt drop off or anything like that, I've got some hairline cracks in one vacuum line which I have to get around to replacing but I highly doubt that this is causing me my boost limit.
other thing is after fitting the damn controller the sound of the turbo spooling up seems to be louder? I do have a feeling the turbo is on the way out because of the excessive movement I felt when I replaced the front/dump pipe but either way shouldnt be effecting me being limited on boost rite?
sorry for all the noob questions but I've asked around nobody seems to be able to help, hopefully someone out there in this forum can help me =)
thanks in advance =)
