Re: average fuel pressure
yea i dont understand why its so high when i only have the stock fuel pressure regualtor with a fuel pump and injectors. the car isnt tuned yet so i guess i need to go and get a adjustable regulator before. and its running rich too.

Re: average fuel pressure
running that pump with bigger injectors on your car will be pushing a lot more fuel thru. Thats why pressure is so high. Get the regulator and adjust before the tune. Thats my .2 cents

Re: average fuel pressure
im runnin a single walbro intank to a bosch 044 to injector Dynamics 1000cc injectors and a crappy B&M FPR.. when warmed up and idling right my Pressure is or can get as low as 20-25psi... when im barely on the throttle drivin down the HWY @ 3k rpm its about 65psi then when i get into the throttle a lil bit more the needle will jump up n bounce off of 80psi n settle around 75psi. .. my old setup was similar to yours but with RC-750's my FP was the same if not a few psi higher than what ur seeing now
