Is my boost gauge working?
So no, you can be at partial throttle. I just suggest rather violent excelleration tests to put more load on the engine so the bypass valve closes, then let off before 4k.
Throttle position is the key to boost with the procharger. The system is designed to bleed pressure off under light throttle conditions. Once you get it broken in press the pedal down and you'll see the boost climb. If not you need to make sure the bypass valve is working properly, it will bleed alot of boost off if it sticks. I had to "tweak" the linkage on mine a little to keep it from sticking.
