The generic tunes that come in tuners can do more damage than good. Go get dynoed and get a tuner made for your car. Imagine trying to tune 10 guitars with the same programmer. I would not work because all the guitars are not starting from the same point.
Yeah I think I am going to purchase the gear kit from MustangTuning.com, it comes with( FRPP 4:10 gears, SCT xcalibrator2, and 3 things of rdline gear lube!). I think this will be a nice little upgrade for the money it runs about $560, then I will just use the tune that comes with it.
