      Increase Horsepower and Torque. Unlock the hidden potential that your vehicle has to offer with an Edge Gas Evolution CS2 Tuner. 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 the Edge Economy, Performance or Tow Pre-Configured Tunes, you will see a noticeable gain in horsepower and torque.

      Adjustable Parameters. The Edge Gas Evolution CS2 Tuner 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 the Edge 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 Edge Gas Evolution CS2 Tuner 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 Edge Tuner 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 Edge Gas Evolution CS2 Tuner includes a USB cable to enable quick updates or upgrades over the internet. It is recommended to update your Edge Gas Evolution CS2 Tuner to ensure you have the latest software updates and calibration files before installation. Updates are available through Edge.

      Data Logging and Monitoring. With a full color, high-resolution display, the Edge Gas Evolution CS2 Tuner makes it easy to read the Built-In Data Logging and/or the Real Time Data, so you can view popular sensor data such as EGT, Air/Fuel Ratio or any other 0-5 Volt source.

      Measure 0-60 Times. Another really cool feature of the Edge Gas Evolution CS2 Tuner 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 Edge Gas Evolution CS2 Tuner 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 Edge 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.

      Application. This Edge Gas Evolution CS2 Tuner is designed for use on 2017-2020 Chevrolet Tahoe models equipped with the 5.3L engine.
