Thread: Rebuilt everything and I need some guidance. (Injectors,gears,e-85)

Exactly youre slope was meant more for a steady state returnless system since your a return style and also under boost your IFR will be a little diffrent.
Id also load in the injector offsets and see where that takes you, Id highly recomend always starting off the injector data per manufacturer inserted. Then you do what you have to do, but atleast your foundation is right IMO

appreciate everything. Some good info, and I was unaware of how the FPR functions in this case between when the engine is in vacuum vs boost. I'll upload the IFRs you mentioned above this afternoon and see how my trims look. I'll post some results to this thread later today or tom.

thanks again! (Feel like I am totally thread jacking at this point. Sorry op!)
