I have a 2011 Ram 1500. I do not like the MDS system in my truck. I want my truck to be a V8 all the time. Does anyone know how to disable this? I'm looking for a permanent solution.

Actually the only true solution is the non-mdd conversion kit for the 5.7 hemi. check out JEGS they have them for under 300. doesn't just turn MDS off it deletes it

It takes every bit of a half a second to hit the Tow/Haul button on the dash. Doesn't cost a dime.

Tow/haul does not turn off MDS on my 2013 Hemi 1500. Hitting the tap shift is the only way I found to get MDS off but only lasts during the current ignition cycle.

Actually, it only lasts as long as the vehicle is in drive. Stop, put the truck in reverse to back up, and then in drive again, in my 2017 at least, I have to use the tap shifters to turn MDS off again.

mds is a waste imo unless your driving on a long trip where its flat and those mds lifters are unreliable

that kit is for non oem ecu applications. it will throw codes and go into a fit unless it tuned for it

I have MDS on my truck I would like to replace with a Milling mdk 100 MDS delete kit for gen3 trucks any good? I don't wound anything to wild if I have to redo the engine with non MDS what the best way to go. I'm replacing the intake manifold with a 6.4L intake, cold air intake, headers.
