With the mods listed below my fuel pressure dropped to 42# at high RPM's. A Racetronix Plug and Play resolved that issue.

It will handle a bit more than 400rwhp. I sprayed a 125 wet shot on my almost stock at the time camaro and fuel pressure was fine, 432rwhp. It can vary from engine to engine, truthfully. If you plan to see more than 450 at the wheels I would definately upgrade, if you think you will be in the 400-450 range you could probably put the car together and check your fuel pressure, you might be able to get away with the stock one at that power level.
