      Increases Power and Performance. Basic bolt-on mods are a great way to increase the power and performance of your 2018-2020 GT Mustang, but you'll still need a custom tune to see the real difference your aftermarket modifications can make. That's where a SCT SF4/X4 Power Flash Tuner that includes (1) VMP Tuning Custom Tune File comes into play. From the factory, Ford programs their Mustangs to cater towards the needs of the daily driver, not the performance enthusiast who adds aftermarket modifications in the search of even more power. By optimizing the air/fuel ratio, adjusting ignition timing and tweaking cam timing, a VMP Tuning Custom Tune will squeeze out the extra power your aftermarket performance mods have to offer.

      VMP Custom Tune. When you order the SF4/X4 Power Flash Tuner by SCT, you aren't just getting a tuner. You're getting the tuner and (1) custom tune file written by VMP Tuning specifically for your Mustang and your particular modifications, you even get your choice of octane level. VMP Tuning provides 1 post sale datalog review (if necessary) to assure your Mustang is running healthy and strong.

      Compact Design. The SF4/X4 Power Flash Tuner measures in at 2.7-inch wide X 5.5-inch tall making it much smaller than the original SF3/X3 for easy storage in your center console or glove box. The cord is detachable and there is no battery or power supply needed. It uses the power from your vehicle's diagnostic port or computers USB connection.

      Full Color Display. The SF4/X4 Power Flash Tuner features a full color 2-3/4-inch diagonal LCD screen with user adjustable portrait or landscape modes. The SF4/X4 also has a convenient power saving auto dim feature.

      Built-in WiFi. The SF4/X4 Power Flash Tuner is now WiFi-capable meaning you will no longer have to plug it into your PC/Windows computer to receive the latest SCT firmware updates. Once setup with your Wi-Fi password, the X4 will download the latest firmware updates via the internet.

      Data Logging and Monitoring. With a full color LCD display, the SCT SF4/X4 Power Flash 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.

      Diagnostics Tool. The SF4/X4 Power Flash 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.
