Message I recently installed a Profec B in my Z32, based on install writeups I've seen on this forum. Install was easy, but the boost controller is not raising boost at all. I even put the duty cycle all the way to 100%, but the boost never went past 11 or 12 psi. I double-checked the hose routing and hookup, and the vacuum lines are going to the correct ports on the solenoid. I also unplugged the BCS solenoids. I really have no idea why this boost controller won't turn my boost up, any suggestions?
