some things that may help the MPG is less weight, and better arrowdynamics weather that is ez too get may be a diff story. The reson a smaller engine gets the same MPG is becue you need more gass too go the same (asooming it has less power). What kind of tires do you have? are they low on air? What kind of rpms are you crusing at? I have heard some of the super chips help the mph... not sure its true tho (also not sure they have them for the monty). On a side note if you want good MPG not sure a SUV is the best thing too drive <img border="0" title="" alt="[Smile]" src="images/icons/smile.gif" /> I wonder if you remove the front drive shaft if that would help the MPG... less drive train loss. But it wouldnt be 4wd unless you reinstall it.... Just some ideas.
