You should run 12psi... Your stock fuel pump can't keep up with your setup.

You'd probably want an AFPR at some point (don't know if your stock regulator can handle the flow), so after that, I'd just get the 255 HP and call it a day. Be sure to wire it so it gets the voltage it needs, too.

How would I rewire the fuel pump

Go to the VFAQ main page, then to Fuel on the top navigation box, and on that page you'll see six guides to the right of "Fuel Pump Rewires". I'd suggest giving them all a read so you'll know how best to go at it.
