This is my third Hypertech, 2010 Silverado, 2010 Camaro & now a 2018 Silverado. I have found these programmers easy to use and quite effective. They offer quite a few options for programming your vehicle to your specific needs. My latest purchase provides the most amount of features to date. I would highly recommend this product if you want to maximize your vehicle's performance, maximize your fuel efficiency and get a solid shift out of your transmission. Hypertech customer service is helpful.
