MDS elimination?

MDS started in 2006 on most vehicles, with the exception of 2500 Ram trucks and a few others. MDS is activated by solenoids in the valley, under the intake. You could simply turn MDS off with tuning and they will never act to deactivate the cylinders. Basically the solenoids hold the exhaust valves open and the ECM cuts fuel and spark to those cylinders.

To fully remove MDS you will need to pull the solenoids, replace them with the truck non MDS block off plugs, then pull the heads And replace the lifters with non MDS and push rods.

I've seen many do just fine by simply turning the MDS system off with a tune, but that's up to the owner of the car.
