Boost has been low for a while now in my opinion & can very from high's of 8.2 psi all the way up to last night 10.8 psi
I unplugged the boost bypass solenoid but could only manage 3.2 psi lol, plugged the connector back in and managed to hit all time high of 10.8 last night. This morning, I can barely get to 9.

How do I test the functionality of the solenoid or actuator?

Also noticed that I don't hit maximum boost until very high in the RPM range...
