Used it on a 2003 suburban and increased the gas mileage on the highway by 2 miles per gallon without feeling any loss of power. Very pleased so far

DI ordered the Hypertech programmer for my 2013 Chevy Suburban 5.3 liter V8,wanted some extra pep for passing, and to give engine litte boost of extra power.Wow what a huge difference it has made,so much better than the granny factory settings.I mean it would get up and go before,but you really had to stomp on it pretty good,i was not satisfied with that though.Now runs like a V8 should run,much more responsive to throttle,rpms much better....i selected all the maximum settings in all modes.

The tuner is very easy to use and it goes step by step for the most novice of people.I like how no mechanical experience (i.e. me) is needed and the preset tunes are ready to go just plug in, make selection,and basically that's it.Also there are advanced options which I am not going to fool with I'm not experienced enough, but I did correct speedometer with just entering tire height.I like how I can hit a button and get noticeable performance/mileage gains,when I step on it she goes now finally!
