One other thing you want to check is the recirculation valve mechanism and hoses. The recirc valve is designed to open and recirculate the charged air back into the intake of the turbocharger. For instance, when you're accelerating and shifting, momentarily closing the throttle body. Now if this valve opens prematurely while your are accelerating hard under boost, charged air into the intake will be lost, circulated back into the area between the turbocharger inlet and metering plate and quite possibly causing the metering plate to close because there is no air being drawn from the metering area. Closure of metering, loss of fuel delivery...... Just a hypothesis ($0.02)
