essentially stops for a split second until you back off the throttle.
No, the fuel pump is working fine, I don't think you can get overboost with a defective fuel pump.
I don't know what you meant by bypass valve, is this the hooter valve you are talking about or the boost pressure control (BPC) solenoid ? If it is the hooter valve, i.e. one without any electrical connector, then it is not the BPC solenoid.
The BPC solenoid sits on top of the radiator fan shroud and has an electrical connector with three vacuum hoses running to various points. A sticky solenoid can give you overboost or in many cases intermittent boost or no boost :-).
If you know someone who has a functioning late model turbo 9000, see if you can borrow the BPC solenoid and test it in your car. You might hit overboost a few times after the switch but the computer would adapt to the new solenoid after a few trials.
