OK. So I've only had my Hemi for 6 days now. Loving the hell out of this MDS stuff! Why? Because I'm coming from a 2003 with a 4.7 that got an average of 14.6 MPG over almost it's whole life. With this new one, I'm getting a solid 15.0 (I reset it on day 1) and I now have 150 more hp (2003 4.7 is rated at 245 hp). And, I've been "punching it" a lot. I bet that'll go up to 16, once I calm down a bit. So, I'm thinking that this is all because of the MDS. Seems like a win/win. So, why are there Youtube videos/posts on here, etc. showing how to disable it? Why wouldn't you want good MPG? How does it make the truck any faster, seeing how it instantly turns on and off?
