FPR question

[Lantz]

if you are running a fuel management system (like enthalpy) is there any reason to get a FPR like the nismo one. I didnt think you had to but ive been seeing setups with both.Also, I dont have my turbo kit on yet but I already installed my walbro 255. Is my car running the correct air/fuel without any tuning/fpr with that fuel pump? because it seems like im goin through gas faster. Just a couple questions i couldnt find the answer to by searching. thanks.

check your fuel pressure to see if the stock regulator is keeping it where it needs to be ~43 wiht the vacuum line disconnected, if its not get an aftermarket one. Ive always used a stock regulator, I could put the money somewhere thats more usefull.

You are running rich. Surprised you haven't smelt gas. Nothign major. But your plugs may foul out, they shouldn't but keep a 5/8 socket in your car just in case you need to clean them off...

I kept the stock regulator.

i needed an FPR on my car to keep it from running way too rich. as it is without the FPR the car likes to die after i flip the car into neutral.

thanks for the info. I guess once my setup is complete ill see how its running and make my decision from there.
