when its idling rev it to like 4k real quick then let it drop and listen for the surge valve...you can hear it cycle...if it doesnt make the little flapping sound then ur line to the valve is messed up...make sure your line isnt pinched either....i had the same problem so we swapped it over to the controller on the driver side, i think its the brake booster, whatever the damn round this is at your firewall!...hook it up there if your not getting good response, normally i get 20 inches maybe 24 at idle and if i rev it it goes to 0 maybe 1 but on the road it goes up to about half boost then climbs as you accelerate.....ill see if i can get a pic of where my line is setup so you can reference that and work with it from there...

You say the crank pulley bolt is tight, are there dowel pins in the procharger pulley to keep it from spinning while in position in the crank pulley? Seem to remember some issues in the past, of either no dowel pins or the crank bolt being just s bit to long.
How is the intake side of the blower, any blockage, or problems there.

It also sounds to me that your bypass valve is not working correctly. I recently had one that would not close far enough. We swapped it out with another ProCharger bypass valve and it immediately picked up two pounds of boost. I would first disconnect the vacuum line, as the line is normally hooked up wrong when this problem exists. If you still do not see much boost, I would then try running the car briefly without the valve installed, to see if it is the culprit.
Let all of us know what you find out. Bob

To get rid of the rattle at idle, i think you should invest in the SD Concepts pulley kit. The rattle goes away and the belt wraps around the pulley even more and also, no slipping. I installed it on mine, and it is a night and day difference. good luck with getting it running right.

A loose belt & loose clamps are the first place to look, tho that only limited my boost to around 4 psi. Have you monitored the boost gauge as your RPMs climb? Does it go to 1 psi at 3k & stay there? Or does it climb up & then drop back down when you hit 5500? (floating valves or running out of fuel)
Is this a new or used system? What are your pulley sizes? Re-torque their bolts (don't just look). Is your dipstick blowing out? Do you have a metal intake plenum? Have you checked it for cracks, or the inner coolers? Throwing any codes? What is your a/f?
Sorry, but there are many things you need to check.
