Need help!!

I got a 2002 Camaro Z28, it has LT headers, air box, and NX 150 wet kit.
Got it dynoed today and it leaned out BAD. My fuel pressure runs at about 55 all the time, but when i go WOT it drops dramatically, why? I am planning on getting heads and cam soon, so what fuel set up would be best for my car?

My results today were 477 hp and 598 ft/lb of torque

thanks

Have you changed the fuel filter? If it's good then your fuel pump might be going. My suggestion would be for the Racetronix fuel pump kit. It comes with a new pump and wire harness. The wire harness is "plug and play" and the pump is a direct replacement for the stock pump, and it maintains the factory functionally of the fuel system. If you have any questions let us know. Below is a link to the Racetronix kit:

Aprox. 600 RWHP until the factory regulator is the limiting factor.

650 ish with a fuel rail mounted fuel pressure regulator. Anything over that you can use a Boost a Pump and squeeze a bit more out of the single pump kits.
