2000 - 2007 Ford Focus SCT X4 Tuner
This is an SCT X4 Power Flash Programmer for your 2000 - 2007 Ford Focus! It gives you the option to have your Focus custom tuned in the future. Remember, when you modify your car with a new intake, exhaust, or turbo kit -- 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.
