Superchips MAX Microtuner

I purchased this Superchips MAX Micro Tuner at first just to improve my fuel mileage during heavy loading. The minimum i load this Super Duty is eightyeight hundred pounds. But what i received was an eye opening experience as to how far back Ford Motor Company cuts the power and performance on these trucks. Not only did i receive a major boost in power and performance. I also was very shocked and pleased to find that it greatly improved the fuel mileage both local and highway. Shockingly it improved by four miles per gallon in town and a greatly appreciated nine miles per gallon on the highway empty and five miles per gallon loaded up to eleven thousand pounds. This truck was ordered to handle a one and a half ton load on a regular basis.I have even increased this more with even more not so expensive modifications. But that would be another review.So this is all for now and thanks for the read.
