the wastegate is fine, it spools and boosts normally, its just when you let off that the problem occurs. I opened the throttle blade a little with the adjustment screw as it was totally closed off at idle. It made it a whole lot better and when I test drove it a little while ago it was great, I set the screw out about .020". My mechanic took it out for a test drive to confirm and it died twice on him. So just to test I taped a .025" feeler gauge behind the throttle stop screw and tried it again. This time it didnt die. I will have to adjust the TPS to the blade though. I may try another .010" and adjust the TPS. Ill report back.
