    07 GT Return style Fuel System

    Working on an 07 GT and we just put a return style fuel system on it. I went through all the injector modifier tables and set them to 1. I'm wanting to know if there is anything else that needs to be switched. I'm used to doing this on coyotes and 03/04 cobras, can't seem to find anything in the tune that jumps out at me needing to be taken off. Any help would be greatly appreciated and would probably help someone else at some point.


    I searched and searched and didn't find anything on this. If I missed it, my apologies and a link that sets me in the right direction would be appreciated.

    when swapping to a return style system you simply set the fuel pump voltage table to all 12s and disable the fuel pump adaptive correction

    wire the stock fuel pump wiring to your new fuel pump relay

    everything works same as stock. Be sure you keep the fuel rail pressure sensor so your ecu compensates for any fuel pressure loss.
