Yeah it would be nice to alleviate the pressure at low fuel flow to help the stock FPR cope but managing the voltage is used on a retunless system....mustangs, GM's etc. There is no scope in my code to modify pump voltage.

I agree, my pumps are hooked up to a relay triggered by the ecu. mabee the program can half activate the relay.

I agree would make the idle pressures much better to manage

The factory ECU grounds the FP relay and the pump is either on or off, how do you vary the voltage to the pump? This could only be done if the +ve feed to the fuel pump relay was running through a voltage regulator/or a current limiting device and monitored/altered via closed loop by the ECU. Can the falcons do this?

Nope........not from factory.

Have 4 044's in my Ute which are boost ativated with 2 running all the time and I think it sound horn/tuff, other xr's/cars pull up besides at ask what the sound is the Ute is lound anyway with the exhuast. Have pull the fuse for 1 of the 2 pumps and the second 1 when reactivated make it about 30% lounder.

anyone got any pics of their Process West surge tank set up with twin 044's?? Pretty keen on this mod myself.
