Accel Performance Handheld Super Tuner

ACCEL's 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 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, or Chrysler vehicle, ACCEL's SuperTuner does all that, too - and for a lot less than you'd probably think.
