Hello
working on a 2007 GT500 with a lot of mods.
car runs good and produce power how the customer like it.
but there is one issue and I can't find the reason.
in the picture below, you can see that with WOT at 5700rpm the fuelpump control modul lower the voltage output and the fuelpressure goes down and the AFR rising up.
is there anyone who know, where is the solve this issue?
I think, I allready worked on every table in the fuelsection... but no change.
installed are Aeromotive 340 Steath Fuel Pumps, they should produce enough fuelmass.
