i currently have in my 5gen I/h/E/8lb fly. i just got a Vafc2 with the harness from my homie for dirt cheap ($75) great condition! (he just decided going turbo) and the other day tearing up my room apart looking for some tools, i found my old B&M fuel pressure regulator with the pressure gauge used in my civic. and guess what, while doing a little research it does fit in my lude so this is my questions

what kind of gains can you see from FPR after tuned by vafc? should i install it or is it a waste of time? at what pressure should i set it? or just leave stock one?

i heard 5gen's run very high in pressure thats why am asking.
any info its Welcome

 

bump

 

just passing along info here, so don't flame me for giving false info! but i heard that a 5th gen (obd2) will alter timing to make up for any irregularities in something like fuel pressure to keep emissions stuff in check. if so, it would be a waste unless you go with a chip or standalone of some sort. anyone want to add onto that?

 

^^^^thanks for the opinion though, you are about the only one, i just would like to know if tuning the car with FPR would make a Diff in the dyno, i guess i have to figure that one out myself.

 

not with those mods, ususually getting a FPR means you need more fuel.

with those mods, you won't need to add more fuel, you most likely need to cut back the fuel which the vafc will do for you once you tune.
