I have had the valve wired open for some time and just dissconnected the sensor. It sometimes sounds like it is closed and the boost only gets to about 12 psi and loud inside the truck. It then slowly goes away and runs great.
What else could it be? /ubbthreads/images/graemlins/shrug.gif

Good luck
