To celebrate 75 years of Jeep® as an American icon, SCT® Performance has worked tirelessly to create dyno-proven, precision performance tunes that empower the 2016 Wrangler to meet and exceed your driving needs. This calibration now comes preloaded on SCT’s X4 performance tuner, so you can experience a boost in horsepower and torque right out of the box.

Like Wrangler, the X4 is all about eye-catching design, rugged dependability and reliable performance. With an easy-to-use push-button interface, X4 puts greater power, better throttle response, firmer shifts, and even increased fuel mileage at your fingertips. There’s also space for up to 10 custom tunes, so you can make sure your Wrangler always exceeds your expectations.
