About This Product
2005-2025 HEMI MDS Delete Tune File
This remote tune file is built to disable Multi Displacement System (MDS) on supported 5.7L and 6.4L HEMI vehicles. This is for customers who want a clean HEMI MDS delete tune, better reliability, improved drivability, and calibration support using HP Tuners. Built from your actual factory read file, not a random one-size-fits-all upload.
Disable HEMI MDS The Right Way
Chrysler, Dodge, Jeep, and RAM Multi Displacement System shuts cylinders off during light throttle driving. Many 5.7L and 6.4L HEMI owners choose to disable MDS for better reliability, smoother operation, improved drivability, and to support MDS delete kits, cam swaps, long tube headers, cold air intakes, tire size changes, gear ratio changes, torque converter changes, and transmission tuning.
- Disables HEMI MDS cylinder deactivation in the calibration
- Built for RAM 1500, Charger, Challenger, 300C, Durango, Grand Cherokee, Magnum, and related HEMI platforms where supported
- Supports 5.7L and 6.4L HEMI applications where applicable
- Works with HP Tuners depending on year, operating system, controller, and vehicle support
- Real revisions included because drivability, logs, communication, and adjustment matter
