2016 Ford Focus RS SCT X4 Tuner

This is an SCT X4 Power Flash Programmer for your 2016 Ford Focus RS! It comes pre-loaded with dyno-proven tunes! Moreover, it gives you the option to have your Focus RS custom tuned in the future. Remember, when you modify your car with a new intake, exhaust, intercooler or turbo upgrade -- you need to have your car's ECU updated to reflect those mods.

All in all, the SCT X4 unlocks your Focus' full performance, this by adjusting your vehicle's computer's parameters for maximum horsepower, better torque, increased throttle response, and overall efficiency.
