We have found the limits of the stock fuel system, stock pressure, stock motor, EVERYTHING stock (even the valve springs), AND on 93 octane, ONE A MUSTANG DYNO. 442whp is the limit to stock fuel pressure. If you know how to tune the car, you can replicate it. Some people find this hard to believe (*cough* ZZP), but this car has been running this for a yr now. Granted, its OUT of fuel at this point, but it still runs like a champ.
So, that said, if you can't make over 400whp with stock fuel pressure, maybe its time to hang up the ol' cable and call it a day?
I don't see many people shooting for over 450 whp, but to those people... keep pushing for this.
