Great addition! More get up with 1-2 mpg more!

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.

This is the first time I have used this product. It was easy to install and it has given my 1999 Silverado 1500 quite a bit more pep. We will see how things progress over time. Excellent customer service from this business. I will come back in the future.
