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?

It's a while since I did mine so I can't remember too well but there are two ports on the solenoid, one goes of to the turbos and one is left open. Have you got the hose plugged in the right port? Have you left the other port open (it comes with a plug in it from the factory)?
