I just installed a FORE stage 4 fuel system with wiring on a 2015 GT with a whipple, 1050x injectors, E85 and 3.65 pulley. We initially ran the car on two pumps because we felt the third was overkill. At about 6800 STFT starting trending up and AFR went to 81-83. I have checked all the wiring and it appears to be good. We added the third pump and it got better but it still seems to be running out at the top of the gears. Where do you guys have your tripple pumps grounded and powered at? Another weird thing is the fuel pressure has changed three times after setting it. I set it with car running and vacuum line off at 55 then check it a bit later and it is showing 51ish.
