Shouldn't. It takes boost to get the wastegate to open. During shifting the boost falls off, just the oposite of what it takes for the wastegate to open.

Well, partially correct... It takes a signal from the ECU to actuate the VSV and allow pressure, from the pressure tank, to move the actuator.

are you sure it works like that on the wastegate vsv? If you follow the vac hose, it goes into the intake, doesnt that vsv bleed air away from the wastegate? If you pull that hose you will get max boost right?
