Do you have a returnless style fuel rail? I am guessing so from the fuel system diagram pic from your sig. If that is true, returnless style rails have a hard time keeping good fuel pressure at the rails once you push 500 rwhp. I would first get a set of billet fuel rails, a regulator, and a return line installed. Having a return style fuel rail setup will greatly help out your pressure.
