I have a 2006 Silverdao 2500 Hd Duramax with Allison 6 spd, I pull a 15500 LB 5th wheel Big Country. It has increased my mileage by 3.5 mpg pulling the camper. The get up and go is more noticeable now than ever before, when you kick the gas its instance response. Should have installed this long ago instead of keeping putting it off would have saved a lot more money on fuel.

I took advantage of the free upgrade E-con to Max Energy promotion and am glad I did. The car seems to be running better and I will know soon whether that helps with gas mileage as well. Install went smooth and was easy. Hypertech updates were easy as well. AutoAnything customer service helped me quickly and shipped it out quick as well.
Works great but...

The Econ works great! Shortly after purchase I bought from Hypertech the Max Energy Upgrade for my Econ. If you have the choice, buy the Max Energy, you'll get better feature for just a bit more money.
