I put a 5 Star tuner in my 2006 5.4l - works great in terms of improving the engine performance. I only use that truck for plowing, so mpg isn’t very goid to begin with.
Since the engine performance change in the 5.4l was so good, I figured I’d put a tunet in my 2011 6.2l, which is my daily driver. Used the 87 eco stock tune. Didn’t change the performance at all (but the 6.2l is great stock anyway), and my mpg actually went down a bit, so I returned it to stock.

my 2014 is used mostly in town driving under 45 mph. before the tuner i was getting 9-10 mpg. i am currently getting 12-13 mpg. if i take it out on the highway cruise set at 65 it will get 15 mpg.
it has 373 gears, so in town driving sucks gas.

17 F250 Platinum. I have the 5 Star programmer with the 87 gas tune. It definitely helped acceleration and overall peppiness, but I feel like the transmission shift points are unrefined. Upon rapid acceleration, it revs high before shifting, but then it shift pretty hard. It just seems as the shifting points need work. Overall, worth the money, especially when running 37s.

5 star can work an economy tune for you. I sacrificed some power in my 2016 but the mileage overall was 2 mpg better overall. The timing curve on these trucks stock is too aggressive and affects mpg dramatically. If you delay the advance the mileage picks up. It's the same strategy ford uses now for the F150 eco mode.

In my opinion it was a large waste of money. Sold the programmer to someone else. It was a failed experiment for me.

I can't see increasing you fuel mileage much if any by adding any type of tuner. The 6.2L is what it is. I knew what mileage was going to be heading into the order process. I do keep track of each fill-up and my mileage just because I enjoy doing so. One thing that may increase it possibly 1 to 3 mpg would be to use non-ethanol gas. I use E10 in all my vehicles and since it came out that is about what I lost.

I already use it in all of my small engine equipment, motorcycles and Mustang GT.
