Please Note: This SCT X4 Power Flash Computer Programmer will only work on US model Focus STs and Focus RSs. It is not compatible with Focus STs and Focus RSs outside of the United States of America due to the variances in fuel quality overseas.
From the factory, your Focus ST's and the Focus Rs'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, but it also makes for a less than thrilling driving experience. The all new X4 Power Flash Computer Programmer from SCT unlocks your Focus ST's and Focus RS's hidden performance potential by optimizing the computer for maximum horsepower and torque, improved throttle response, solid shifts and even increased fuel mileage.
Since it's launch, the Ford Focus ST and the Focus RS has been praised for driving performance and utility and the aftermarket has been catching up to make the Ford Focus ST and Focus RS even better. CJ Pony Parts now offers many Focus ST and Focus RS parts, giving you the opportunity to add an exhaust, springs, appearance items and more, making it even better. Order your parts today!
