The next generation handheld tuner for the 2013-2018 Ford Focus ST and 2014-2017 Fiesta ST is here, in a big way! Introducing the all new X4 Power Flash Computer Programmer from SCT!

From the factory, your ST's computer is calibrated for the general public, designed with the average driver in mind, not the performance driver. This not only leaves valuable horsepower and torque hidden inside your Focus or Fiesta, but it also makes for a less than thrilling driving experience. The all new X4 Power Flash Computer Programmer from SCT unlocks your ST's hidden performance potential by optimizing the computer for maximum horsepower and torque, improved throttle response, solid shifts and even increased fuel mileage. And with preloaded tunes, your ST is ready to go as soon as you hook up your SCT tuner!

Please Note: This SCT X4 Power Flash Computer Programmer is designed to be used with a single vehicle and ships with a license for one VIN and will only work on models meant for North American distribution. It is not compatible with models outside of the North America.

Tech Tip: Take the time to download SCT's LiveLink and Updater Software. The LiveLink Software app allows you to view, data log, record and playback your PCM data on a laptop computer. The Updater Software allows you to update the BDX's firmware, tune revision or load custom tunes onto the programmer.

Since their launch, the Ford Focus and Fiesta ST have been praised for driving performance and utility and the aftermarket has been catching up to make the Ford Focus and Fiesta ST even better. CJ Pony Parts now offers many Focus and Fiesta ST parts, giving you the opportunity to add an exhaust, springs, appearance items and more, making it even better.
