      More Power and Better Performance. Enhance the power and performance of your 2018-2020 GT Mustang with a SCT Rev-X Tuner that includes (1) Li Tuning Custom Tune File. From the factory, Ford programmed the Mustang to cater to the needs of the daily driver, not the performance enthusiast who adds aftermarket bolt-on modifications in the search of more power. Whether your Mustang is bone stock or you have added a cold air intake, throttle body, exhaust, other bolt-on performance upgrades, or are running an aftermarket intake manifold, you'll need a Li Tuning Custom Tune to see the full power potential that your aftermarket mods can make.

      One Li Tuning Custom Tune File. When you order this SCT Rev-X Tuner, you aren't just getting a tuner. You're getting the tuner and 1 custom tune file that has been written specifically for your Mustang and your particular modifications by a Li Tuning calibrator. Li Tuning calibrators their tunes for all around drivability, not just WOT performance, so you'll see an improvement in low-end torque and increased throttle response. By optimizing the air/fuel ratio, adjusting ignition timing and tweaking cam timing, a Li Custom Tune will squeeze out the extra power Ford left on the table. This tune requires the use of 91-93 octane fuel or E85.

      WiFi Updates and Cloud Tuning. The Rev-X Tuner by SCT is Wi-Fi capable meaning it will always be up to date. Once setup with your Wi-Fi password, the Rev-X will download the latest firmware updates via the internet. Besides firmware updates, your Rev-X can also download your custom tune files via the cloud, reducing the hassles of transferring files from your PC to your Rev-X device.

      Data Logging and Monitoring. The Rev-X Tuner by SCT 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. You can even customize the monitoring capability of your Rev-X using device's free Livelink software.

      Diagnostics Tool. The Rev-X Tuner can also be used as a diagnostic code reader. Save yourself hundreds of dollars each year 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 custom tune on the vehicle, the tuner automatically stores your vehicle's factory settings. To return the vehicle to its 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 SCT Rev-X Tuner that includes (1) Li Tuning Custom Tune File is specifically designed for 2018-2020 GT Mustang models equipped with the naturally aspirated 5.0L V8 Coyote engine that are stock, have basic bolt-on modifications, or an aftermarket intake manifold installed. Aftermarket camshafts, and/or ported Heads are not supported with this tune.

      **Please Note: The Rev-X ships blank from AmericanMuscle, the custom tune file will be emailed directly to the end user within 5-10 business days from Li Tuning.
