Ian , I think you have got your wires crossed here.... "Boost pressure neg deviation (under-boost)" Mark you need to test the complete induction system for leakage of boost pressure. the slightest discreet leak will flag this fault.. it's very rare for a VNT to fail in the low boost position. It normally the control side has leakage or the boost side as leakage...
