18psi tune needed
18psi tune needed
03' built 5.4 on 18psi ati... i've been looking at www.rffperformance.com as they are locally to me but not sure who i should go with.
when you say "built" what all have you done to make your motor, trans and rear end live at 18 psi and what kind of gas are you going to run?
just figured out who you are, no need to answer my question.

Rff is reputable amd anytime you can have the tuner and your ride together on a dyno thats the way to go. There is way to much margine for error via mailorder when you have substantial mods. Given the choice to use a local reputable tuner or mail order I would go local any day. Your lucky you have someone local, I dont and have to wait for them to come through town, kind stinks.
