The Range MDS Manager allows your Hemi-equipped vehicle to run in 8-cylinder mode at all times, preventing the Multiple Displacement System (MDS) from dropping cylinders. Our patented technology is the only product that will disable MDS without reprogramming the factory ECU. Full power delivery all the time without factory warranty concerns.
- No more shuddering as your engine cycles between running on half or all cylinders
- Improved power at light throttle with all cylinders firing which can actually result in improved fuel economy depending on your driving habits
- Dodge's troublesome MDS valve lifters will no longer be tasked with activating and deactivating constantly, saving you money on costly future repairs
