2005 - 2014 Hemi MDS Multi-Displacement System Delete Programming Service

This is a service to disable the Multi-Displacement System on Hemi Engines. 

Send us your engine computer and we will permanently disable the system.  You will no longer have to worry about having the engine shutdown cylinders making the vehicle feel sluggish.  Your engine will always run on 8 cylinders. 

Many people elect to disable this system especially after modifying their vehicle.  This is one of the first things that people remove due to the issues that the systems have as well as the lack of power when the system is active. 
 
After purchasing please send your computer to: 

GARRETT TUNING

We will perform the service and send it back to you.  Programming time is usually one business day.

If you need a computer supplied for you or have any questions please do not hesitate to call us or send us an email. Please have pictures of your computer handy as we may ask you to send us a picture of the tag of the controller.
