      Description

      Increases Horsepower and Torque. Increase the power and performance of your Yukon with an SCT SF4/X4 Power Flash Tuner that supports third-party custom tune files and includes pre-configured SCT strategy tunes. From the factory, GMC programs their vehicles to cater to the needs of the daily driver, not the performance enthusiast who adds aftermarket bolt-on modifications in search of more power. After loading a SCT pre-configured tune, even a bone stock, unmodified Corvette you will see noticeable gains in horsepower, torque, and fuel economy.

      Compact Design. The SF4/X4 Power Flash Tuner measures 2.7-inch wide X 5.5 inches 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 computer's 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.

      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 an SCT pre-configured strategy 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.
