My hp will max at 500 or so.

i would check the rubber lines on the back of the motor an make sure you dont have any leaks.. would prolly be a good idea to check pressure

It's got new lines and a new lift pump. I have a gauge on the pump, its read 20psi +/- at idle and over 30psi at 2000 rpm. But I get the feeling that I'm just not getting the fuel that I should to the injectors.

I have a about 1/4 mile upgrade that I use for testing. I get some smoke at lauch, but as soon as the turbo starts spooling, it clears right up. With my plate and AFC ff, I'm max'd out at 1350 egt and 40 psi boost (wastegate pinched) at the top of the grade, with barely at trace of smoke. I know it sounds like a perfect street setup, but it just seems like it's not getting the fuel that it should.

This weekend, I'll probably move the gauge so I can read it while I'm driving. That should help me figure out what's going on.
