·Ok, Ive used the search function, called dealerships across the country and still have no firm answer... Here goes: Does a Power Commander or TuneBoy offer me any performance tuning other than chosing a map for high or low mount exhaust for my 98 T509? If possible I would like to get a little more out of her.
If this is :horse: then go ahead and :finger: :violent1: Thanks
