mpg in an suv nope....im sure there has been people to try but honestly its a brick so there isnt much gas saving in it unless you drive like a pawpaw.
a good drop in filter (oil less)
free flowing exhaust you can keep the cats
a mild tune to take advantage of the low end timing to help get it moving
gears/lighter wheel combo
or just do like me an not give a damn about mpg an drive that thing
