Easy installation, love the auto tranny shift firmness adjustability and yes actually I can notice a performance increase

Bought it cause I put 35's on my Tundra and I was about 5mph off comparing to GPS. Also noticed shift points were off along with gas mileage. This calibrator not only allows you to fine tune the speedometer but it also brings the shift points back to factory settings. I am now back to 18+mpg on highway and 13-14 aound town and I am heavy on the right foot. Easy install, just make sure to zip tie to prevent rattles behind the dash. Highly recommend.

Taking from some of the information I found on a few other reviews and articles, I was hoping the Max Energy 2.0 would resolve the "chuggle and hesitation" on my truck (a known problem that GM will not or can not fix). While it did help on the city driving issues, the highway speed hesitation is still a problem. The programmer is pretty easy to use if you read the instructions first and follow the on-screen instructions. I like the five program option. I currently have two loaded.
