Accel SuperTuner Performance Tuner; 2.8 in. Color Screen; Find parts that fit my vehicle

ACCEL's all-new SuperTuner boosts power across your engine's entire rpm range. You want noticeably better fuel mileage at partial throttle and more power than you've ever had at wide-open throttle? The SuperTuner gives it to you. Want the security and peace of mind of a 2-year limited powertrain warranty? The SuperTuner handles that, too. How about instant throttle response, firmer shifts when you're towing a trailer, and a whole host of user-controlled features? If you have a GM, Ford, Dodge, Jeep, or Ram vehicle, ACCEL's all-new SuperTuner does all that, too – and for a lot less than you'd probably think.
