Not sure if this will answer your question but when I had my 2006 charger R/T I used a diablo intune and kept MDS on for a week and my MPG never moved, but I was tired of the annoying drone my exhaust emitted and decided to turn it off, within a day it dropped 2 MPG and stayed there unless I turned it back on. Could have been the way I drove it too lol. Hope this sheds some light and gets some more qualified answers for you!!
