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.
