Hey Guys,
I have a 2014 Sierra with a 5.3 and 72mm turbo with about 8PSI, cast pistons, and crank.
I am having trouble with the fuel rail pressure never really getting to the "Desired pressure", as the RPM rises it gets worse till it misfires and falls on it face.
Any thoughts on how much I can turn up the settings on the Fuel pressure tab? or maybe I am missing something completely.
Any help would be appreciated.
