The Jeep Grand Cherokee HEMI combines rugged capability with powerful performance, but the factory Multi-Displacement System (MDS) often leads to issues like lifter failure, ticking noises, and reduced reliability. Our MDS Delete service permanently disables cylinder deactivation in your PCM, keeping all 8 cylinders active for consistent performance.
Ship your PCM to MoPower Calibrations or visit an authorized MoPower tuner. We reprogram the ECU to permanently disable MDS, ensuring your Jeep Grand Cherokee delivers consistent V8 performance. No wiring changes or external modules required.
