Is the wastegate manual or automatically controlled? I think using throttle position to control MP and the wastegate only as a safety to prevent overboost might be the answer. If achieving the right amount of boost is a problem, I would look into a rich mixture problem (lower exhaust temp causes less expansion of the exhaust gases therfore lower rpms of the turbine buckets). The turbo could be sized for a car application, and boost may not come in until 4500 rpm or so. you could be experiencing compressor blade stall (surge) but would probably see an eratic manifold pressure. Hope you get the bugs worked out!! Best wishes Riley Collins Rutledge, TN
