Hey I need some Bigstuff3 tuning help.. New to the area. I have a 91 Mustang drop top with a supercharged 331. I am using the Big stuff 3 to tune the car. It is a stand alone computer like a F.A.S.T system or accell DFI. Most turbo or supercharged race cars out there are running this setup. Let me know who are the tuners in the area. I figured with the 2 local tracks there has to be some racers in this Forum.
