HEMI MDS questions

I hated MDS on my Magnum, felt like the trans was slipping or pulsing. I thought something was screwed up because everyone says its not something you can feel but i disagree completely. Got my Diablo, turned it off...no more twitch.

The best i averaged on a long trip was 23.5 MPG w/ MDS. With it off, i got 22...
maybe they made it more seamless later on as my Magnum is an 05 but i say good ridance to it.
