      Description

      SuperTuner for Superior Performance. Give your Silverado 2500 HD an outstanding performance by installing this Accel SuperTuner. This handheld tuner integrates with your ECU via your ride's OBDII port allowing you to gain access to your truck's various system parameters. This factor gives you the ability to adjust your ride with the device's preloaded tunes optimizing its performance to the specific driving scenario you find yourself in. This tuner is also capable of uploading your factory tune allowing you to revert to stock when needed.

      Economy Tune for Practical Fuel Savings. This Accel SuperTuner provides you with increased fuel economy via its Mileage XS tune. This tune is engineered to dial down your truck's performance for maximum fuel economy when using 87 octane fuel. This feature translates to practical savings at the pump without compromising the driving feel.

      Handheld Easy to Use Design. This SuperTuner is designed for easy one-handed use courtesy of its handy form factor and tried and true 5-button control. This design when combined with its 2.80-inch full-color display makes navigating its various functions really user-friendly.

      Make the Most Out of Your Upgrades. Upgrading to larger wheel and tire combos or a higher gear ratio can alter your speedometer readings and thus make shifting less optimal. This tuner gives you the capability to calibrate your speedometer to these new upgrades so it always reads true. More importantly, this speedometer recalibration ensures any shifting issues become a thing of the past.

      Read and Clear DTCs and More. This tuner is also capable of reading and clearing any diagnostic trouble codes (DTCs) and thus deactivating any check engine lights you may be experiencing. What's more, this tuner performs this function while also providing an explanation of the trouble code. This is important in case you experience a persistent check engine light as it gives you an idea of what issue you're experiencing.

      Performance and Towing Tunes. Providing your truck with its gains in horsepower and torque are preloaded performance and towing tunes. Specifically, this tuner includes tunes that will work with 87, 91, and 93 octane fuel, as well as light towing, heavy towing, crawling, and extreme tunes. With all these choices, there isn't a driving application your truck cannot handle.

      Adjustable Parameters Include:

      • Read and Clear DTCs
      • Speedometer Calibration for Tire Size
      • Speedometer Calibration for Gear Ratio
      • Active Fuel Management Disabling
      • Shift Point Adjustment
      • Shift Firmness Adjustment
      • Speed and Rev Limiter

      Updateable via PC. This SuperTuner tuner is updateable via PC software. This allows you to always run the latest firmware for maximum performance.

      Application. The Accel SuperTuner fits all 2007-2015 6.0L Chevrolet Silverado 2500 HD models.

          Easy to find what i was looking for. Lots of great photos, and even able to match the year, make, model, and color of my truck for great reference to what the product will look like installed on my truck.
