Hypertech Max Energy 2.0 Programmer
it seems like a good product but i am disappointed in what function are ACTUALLY AVAILABLE for my year and model truck. the advertising is a little confusing as it shows all the functions and then says choose your vehicle, not knowing that all these functions may or may not be available for your model. It does program nicely.
This is my second superchips tuner I have purchased, one for a 2009 Sierra and this one for my 2013 Sierra. Combine this tuner with a good cat back exhaust and cold air intake setup and you can tune your truck to run the way you want. Very happy with the ease of use when connected and making changes. No going to the dealer when installing larger tires to get the speedometer reset.
