Performance tuning covers your Jeep’s economy, daily driving, sport and towing capabilities and can afford you more mpg at different throttle. A computer programmer calibrates for your specific application so you can take advantage of diagnostic readings and be ready for the road or off-road. 4WD carries programmers by heavy hitters like Superchips and Hypertech that fit a wide variety of Jeep models. These units have varying features including plug and play-ability, Internet updatability and expandability to add aftermarket lights, cameras, lockers and more. Head those trouble codes off at the pass with a reliable computer programmer.
