This is a great tuner and installed very easy with great instruction. We can tell a huge difference in performance.

I wanted to turn of AFM on my 2009 Silverado and to read codes. I have not loaded any tunes so I can't comment on that. The Hypertech Max Energy 2.0 Programmer is very easy to operate and it took little time to learn it. Before I hooked it up to my truck I updated the unit from the internet. Even though it's brand new there were a couple of updates. So I suggest updating it as soon as you receive it. I'm very glad I bought the programmer.

Worked as advertised. My calculations say my tires are 34". With truck weight they measure about 33.5. That is the number I used and it put GPS spot on. Truck seems to be shifting back into 4 cal mode more regularly now helping to boast mpg. Worth the investment.
