S.C. Express will become famous soon enough

With mine I have found the the mds to be worthless in town, 14 mpg avg.. I get better mpg's in town limiting the tranny to 5th gear. The mds requires too much throttle input for in town driving. On the Highway the mds shines. I have gotten 22mpg running a steady 70-75 on fairly flat interstate, even seen 24mpg at 65mph. I ran 80-85mph from Florida to S.C. and averaged 17.8mpg's, all this was done running 87 octane with the a/c running constantly. My truck is still bone stock unfortunately.
