    The digital revolution has just arrived on your dashboard. Celebrate technology at its finest with a SCT X4 Power Flash Programmer (49-State Legal), the most innovative tuner in the SCT lineup. More compact and ergonomic than the X3, the X4 boasts a brilliant full-color LCD display that puts huge horsepower, torque and throttle response gains right at your fingertips.

    Packed with dyno-proven tunes tailor made for your ride, the SCT X4 Tuner unleashes your full performance potential. But that's just the beginning. With full control over a wide range of critical engine parameters, you can create and store up to 10 custom tunes for any situation, from towing trailers up steep grades to passing slowpokes on the highway.

    You don't have to get your hands dirty installing the SCT X4 Flash Tuner. Just plug it into your OBD-II port, follow the on-screen prompts and you're ready for action. Plus, it doubles as a digital gauge set, giving you real-time readouts of all your key speed stats. And with WiFi built in, you can update your X4 without ever connecting it to your PC. It even comes with a 1-Year Warranty.
