    Hey guys,
    I'm upgrading my old 195 pump to a 255, and going the recommended route of adding in a fuel pressure regulator. Currently car is tuned for 20lbs on a 16g and FIC 750's. First question, is the recommended FPR psi still the 41-45 range? And second question, will I or should I need a retune after this or is it still ok to run on the previous tune?
    Thanks for the input.
    John

    You shouldn't need a tune if you set it to whatever pressure the car was tuned on..

    Right so since the car didn't have an adjustable FPR when it was tuned, it should be around 42-45 psi?

    No need for a return line either, just use the return line "mod" to the small brown plastic thing attached to the return in the tank. I cant remember the size but I THINK it is a 1/8 drill bit you drill through the current hole. Basically you are oversizing it. Just try to do a search on here and I am sure you will find it. I think it is included in the fuel pump and fpr install writeup forum under fuel.

    43.5 psi yes. You will not need a retune. Buttt if you wanna add sum more boost and fuel, you would have the pump space to do so.

    yea the new pump and fpr will just help for my new turbo setup a little further down the road. Just hoping to take care of a few easy things myself before I send it out.
