I have a 1999 Mustang GT. It has little things like Cold Air, Underdrive pulleys, flowmaster cat back exhaust, lowering springs, bf goodrich 285's, 4.10's. I am going to be buying a tuner very soon i am just asking for peoples opinions on these tuners. Thanks
If I was going to buy one it would be a diablo tuner. Personally I think there overrated. But that's my opinion. I don't have one and don't plan on buying one. But good luck with your stang hope everything works out for the best.
