Easy to set up. Easy to program vehicle. Better acceleration; better power; some increase in MPG. Almost like having a new truck.

I have a 15 F350 and changed from the stock 34" tires and went to 37" tires and installed the Speedo Calibrator. One thing to remember when entering tire info even if you look up the numbers in height. The stock tires are 34.1" vs the 36.54..you need to measure once the tires are installed on the truck and on level ground. My 37's once compressed are about 36.25 Entering this number got me closer to the real GPS on my phone vs running 2 mph slower at 75mph. Ill be using 35.75, to get it closer.

I was very pleased with the E-CON. I installed it on my wife's 2011 Expedition. I wasn't concerned about the 40 extra horses, but bought it to improve my mileage. I checked the mileage on several trips without it and then with it. By the vehicles mileage indicator, at 70 mph on cruise, I got a 2 mph increase, from 20 to 22mpg. What surprise me was at 75, the mileage went from 18 to 21.5mpg. If you put the pencil to it, the E-CON will pay for itself within 10,000 highway miles.
