Yeah, it's got a Hemi in it.

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.

  • Improved power at light throttle with all cylinders firing which can actually result in improved fuel economy depending on your driving habits

You paid for a Hemi, so you deserve to have 100% of your Hemi's power on tap at all times.
