Paul,
Justin over at VMP figured out a way to re-wire the stock fuel pump for a 10% drop in duty cycle:

This was with a 06 Mustang GT w/ an intercooled Whipple running @ 7.5psi (3.825" pulley).
Hope this helps,
Mike

Before the wiring upgrade FPDC (Fuel Pump Duty Cycle) was at 95% at 6500rpm. After the wiring upgrade it dropped to 85%, the fuel pump required almost one volt less at peak fuel flow (about 4.6lb/min). This car was making 420rwhp with a 11.5:1 A/F. I then tried a smaller 8.5psi pulley, still had plenty of fuel (about 91% DC). With the 3.325 (10.5psi) whipple pulley the stock pump is finally on the edge.

You can use just (1) gt supercar pump and a wire upgrade cost me 139.00 for everything !! Im putting down 487 at the rear with a novi2200 set up ...been running this for over a year now ! (I have 39 lb injectors also)
dont use two of them ..nothing but problems ! you also can use a k/b boost a pump on top of that to !

RE: what fuel pump will support 500hp?
I am pushing 500RWHP with a BAP and stock pump.
no problems, and that is what a wideband and fuel gauge are for anyways.
I am not impressed with what I read on the dual GT500 pump setup.
If I upgrade I would go GT supercar pumps.
