You should run 38 psi with 24 # injectors I make more power than you and my car runs a little rich on the dyno @ 38psi.

You really never have to boost the fuel pressure past 38-40 psi unless your injectors are too small. There is more to how much fuel your engine gets than just fuel pressure. 24 # injectors can support over 400 RWHP @ 38psi on a mass air car.

On mass air cars the ecu will adjust the pulse width of the injector to compensate for more air flow.
