What Activates The Boost Solenoid S5TII

Having a problem with the boost on a S5 TII. Solenoid fine, but when checked at ECU, 2 volts at idle and normal operation, but when under full throttle, no increase in voltage, or pulsation noticed. Not the ECU as I have tried 2 and the boost remains at @ 5.5 and no higher. Before this phenomenon, the car was running 10/11 lbs.(GForce ECU).

Anyone know what input is used to activate the solenoid?
