"Hypertech E-Con At first I was very skeptical as most are when promised better gas milage. I installed the unit before going on a road trip of almost a 2000 miles and tracked MPG both ways------So far so good as I picked up 10- 15% better milage and that was with bucking a 20-25mph headwind coming back. 2005 Chev/Duramax Pulling a 27' Cougar 5th wheel (aroung 10000 lbs) I showed improvement when not pulling (maybe 10%) It actually seems like the better improvement is coming from when I'm pulling a load. So Far, I'm totally recommending IT!!!!!!" —David M from Saint George, UT bought a Hypertech Max Energy E-CON for a 2005 Chevy Silverado.
