Selling a Bully Dog GT Tuner and unused H&S Pyrometer. Moved to a H&S Mini Maxx tuner to delete DPF. Nothing wong with unit. Programer has been unlocked and returned to stock. Unreal power with DPF present. Increased MPG from 11-12 to 13+ in the city and 17+ on the highway (hand calculated). Works on Ford, Dodge, and GM diesel trucks. Would cost over $700.00 new. Looking for $575.00 shipped.
