Accel SuperTuner (07-09 GT500)

Increase Horsepower and Torque. Unlock the hidden potential that your vehicle has to offer with an Accel SuperTuner. When your vehicle rolled off the assembly line, the manufacturer programmed it to the needs of a daily driver and not the performance enthusiast. After loading one of Accel’s Pre-Configured Tunes, you will see a noticeable gain in horsepower and torque.

Adjustable Parameters. The Accel SuperTuner features end user-adjustable parameters so you can further customize the tune to maximize the performance of your modifications. These parameters can be adjusted on Accel SuperTuner Pre-Configured Tunes and/or the stock tune. Please note not all adjustments are available on all models/vehicles.

  • Active fuel management control
  • Tire size adjustment
  • Axle gear ratio adjustment
  • Shift point and firmness adjustment
  • Speed and rev limiter adjustments

Compact, Convenient and Efficient. Featuring a full color, 2.8-inch high definition screen, this Accel SuperTuner has a slim, sleek design that makes it easy to handle and store in your center console or glove box when not in use. Not only is it compact, but its exceptionally graphic interface provides an improved user experience, when compared to the older SuperTuner models. Powered by your vehicle's OBD-II port or USB connection when connected to your PC/Windows computer, this Tuner features increased memory with a high speed processer to provide extraordinary tuning and updating speed.

Internet Updateable. The Accel SuperTuner includes a USB cable to enable quick updates or upgrades over the internet. It is recommended to update your SuperTuner to ensure you have the latest software updates and calibration files before installation. Updates are available through Accel.

Measure 0-60 Times. Another really cool feature of the Accel SuperTuner is that it allows you to measure your 0-60 and 1⁄4 mile elapsed times. By keeping track of your 0-60 and 1/4 mile times you can see the difference your latest go fast mods have made.

Diagnostics Tool. The Accel SuperTuner can also be used as a diagnostic code reader. Save yourself time and money by reading and clearing your own Diagnostic Trouble Codes (DTCs) rather than paying a dealer to do the same. It's as easy as a few simple steps.

Easy to Load; Easy to Restore. When you load your Accel tune on your vehicle, the tuner automatically stores your vehicle's factory settings. To return to the original factory settings, just plug the tuner back in, select the option to restore the factory settings, and you're done. This is ideal for visiting dealerships for warranty work.

CARB Certified. The Accel SuperTuner is 50-state emissions compliant, meaning you can enjoy more power in states with CARB restrictions like California, without any headaches or worry. CARB EO Number: D-745.

Application. This Accel SuperTuner is designed for use on 2007-2009 GT500 Models.
