my stage 3 closed loop saff has a bit of a problem........ it seems to hit overboost in fifth gear but, as far as im aware overboost cuts the boost off by closing the amal valve? my car seems to completly shut down untill you let the revs drop right off to idle speed the and only then can you rev it again.

I wonder if the closed loop part of the system can shut the management down if it detects the car is running weak or somin? its holding 1.5 bar, which is right, and i dont understand why it only does it in fifth gear...its only ever done it in forth once.

Any ideas???? i fed up with it now!
