Ackbarr00:
Are you sure that the FMU adds to the static fuel pressure.
I have used the analyzer, on this website, and it calculates the fuel pressure required to support 300hp with 19 pound injectors to be 64psi, and that a 12:1 FMU is required.

Additionally the 12:1 FMU was standard in vortech's entry level kit (A-trim), and as this kit does not require any additional fuel mods, I would find it hard to believe that a stock 88lph fuel pump would be able to function if pressure under 6psi of boost was spiked to {12*6 + 39psi }= 111psi

I don't mean to question good advice as it is always appreciated, however I am just trying to figure this thing out.

Thanks.
