Aeromotive FPR What to sit it at?

[Silver99GSX]

well im running a Aeromotive FPR with a 2.3L port'd head, 880cc injectors , a 255 pump and a GT35R what do you think i should set my FPR at? I know that the stock is set at 43.5, but with my set up what is thebest to set it at?

43.5 psi

You shouldn't need to change the AFPR from factory settings except in certain situations, like trying to squeeze a bit more out of injectors running at maxed IDC's (in which case you should just get bigger injectors), increasing the atomization of the fuel a bit on super-tuned setups, or possibly to optimize a fuel pump in very specific situations.

Changing it from what the ECU expects just adds one more variable to deal with that isn't necessary.

what about a first gen in that case? a 1990, isnt it 37 psi?

1G - 37 psi
2G - 43.5 psi
