It happened in my f150 5.0 2013. Already 2 months. I just drove 100,000 miles and this programmer improved my truck's shifting and response. It means using the mid-range when tuning your ECU. I love all the live dates you can see. This is accurate for my dash gear temp and speedometer. You read the same thing. As for the increase in fuel economy per gallon, I'd say I'm about a mile per gallon better in the city and about 3 miles better at 65-70 on the highway.
