Dodge added the MDS system in 2006, so any hemi motor 06 and newer has MDS. 03-05 is non MDS. Having said that, the tuners do not change whether you have an 2003 or a 2010...they are all the same.
Not to be a jerk but this is not true. I am about 99% you can delete MDS option when you order a 1500 or at least you could at one point if you can't now and on 2500 and larger it does not have MDS. There is no up charge for MDS when it is indeed available for a particular model.

Used to be the 3/4 and 1 ton hemi trucks did not have MDS in '06. Maybe that's true in 2010? Research Diablo as well, I've got a nice dyno tuned 2010 program.
