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.

For appearance: The unit is build and look cheap! The bottoms get stuck! Like a kid toy! It should look better for over a $300 unit! Using: it's easy to plug in and save the original settings but, when going in to change setting for towing or anything else and unless you know what to do, there is no way you can do it your self without experience and knowledge of what it's asking you ( stock or ..?). This unit needs to have a better reading material or something on the Web site! I need help!!!!

Bought this to disable the AFM on a 2007 suburban, easy to use even if you are not too technical. Worked great, installed the 87 octane tune and modified to disable DOD (AFM). Also firmed up trans shifts and took the top speed limiter off. If you are lookinjg to disable your AFM this does it easily!
