fuel pressure advise

35-40 with vaccum off

32-35 seems pretty low i would start around 37-39 and see how she runs

The pressure should be set at the stock setting - measure it at warm idle with the vacuum off the regulator and plugged - 38-39 psig. If it's misbehaving it's likely because the calibration on the C&L isn't the most accurate in the world. Someone who knows what they're doing in the tune department can help you with that - but your money might be better spent on a better maf. You might also try clocking (rotating) the maf so the air hits the wire differently. Make small changes, and drive it for a day or two before making the next change. Keep records so if you move it into a position that's really crappy, you can back to something that works better. And remember - the computer 'learns' about new operating conditions and adjusts. So drive it for a while before drawing any conclusions about how your clocking change is working.

If you have the stock pump -- well, it's barely adequate to keep up with the stock motor, let alone with a HCI set up like yours. Find out what pump you have. If it's stock you need to move up in size.
