Always better to reprogram instead of tricking the computer.

2014 GMC Sierra 1500. Fairly easy installation. Manual days you need to remove several fuses, but this is not necessary. Just make sure headlights are off, radio is off, and nothing is plugged into DC outlets. Did what it said!

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.
