Run the factory pumps. They will supply enough fuel to 650HP..
As far as a retune>> You lost me? Are you installing larger injectors? Larger fuel pressure regulator? The fuel pressure is maintained by the FPR. For a relative stock engine the stock pump can handle the fuel FLOW requirements.
Log your injector duty cycle to give you a insight to where your fueling is.

ok fair enough, thanks. All my forced induction and tuning experience has been with a returnless fuel system in which the ecu is far more active.
I plan to pick up the Bosch 67493 pump.
Thanks Kevin.
