Low boost problem with p600b procharger
I have a procharger p600 on a 1987 L98 corvette Tuned port and all I can get out of it is 5-6 pound of boost. According to my pulley setup that came with the kit it should make 12 psi. The kit is used and my engine is stock. Has any one had the same problem?

You'd get a lot more help with this in the Power Adder forum.
There are quite a few reasons you could be low on boost, so calling ProCharger would be your best option.
In the meantime, anything you've done to make your engine flow better, such as intake, heads, cam, headers, or exhaust will reduce boost.

Sounds like a serious boost leak or slipping belt. I would double check all the hump hose connections and look for black belt debri on the underside of the hood.
