[thatkid]

what FPR is everyone running? i need to get one to control my wally 255 but i don't know which one to get or even what to look for. im trying to go as cheap as possible. i know i can get one for $20 and i know i can get one for $200 but what exactly is best and what will do just fine? thanks in advance.

You need to make sure whichever one you get can adjust fuel pressure up and down (some only adjust one direction) and that is raises fuel pressure on a 1:1 relationship with boost. So, if base is 36.3 psi and you're running 20 psi of boost, at peak boost your fuel pressure should be 56.3 psi.

You can do some searching on here as to what brand is best. Most people on here will suggest Aeromotive AFPR's as they're proven. Yes, they're a bit more money than others, but a lot of people would rather spend a bit more than have this part fail. I could cause some ugly results if it does.

I have owned both an aeromotive and an AEM.

I prefer the AEM because it is smaller in size and in my engine bay space was limited.

I have aeromotive works great had mine a few years now, worth the money.

thanks guys

so would any EFI fpr work? such as there is a craigslist ad locally for an aem fpr used on an acura integra.

sorry if these questions seem obvious.... fuel management is one thing i have never messed with on cars.
