"No problems with install, was easy and straight forward. My only complaint with the unit is for the price is does not have enough options. If there could be more, it needs to be added to justify the cost." —Scott M from Evansville, IN bought a Hypertech Max Energy Programmer for a 2006 Hummer H2, 6.0L V8.
"easy to install and program. a noticable increase in acceleration. have not yet driven enough to tell if there is any increase in fuel ecconomy. it would be helpful if the directions included how to set up for different performance settings.ie; best fuel ecconomey, towing/ not towing, or pure power." —Wayne J from Yulee, FL bought a Hypertech Max Energy Programmer for a 2006 Hummer H2.
