Car is fast, it is not in limp mode but there is no peak boost..it goes to 0.8, 0.9 bar on 3000rpm and holds almost until redline..then drops to 0.7ish on 6500 rpm..
So higher rpm boost levels seem just fine, but there is no peak boost on 3000 rpm..it used to peak boost at 1.4 bar...
So i made a pressure test...disconnected the actuator hose from n75, and blanked that hole on n75 valve..so now ECU cant control boost..so i was very careful and booted it..goes to 1.5 bar peak..probably more but i didt want to do that..
So there is no boost leak...could a broken(partly broken?) n75 cause this kind of behaviour?
