programmer for a mainly stock truck

I have a 2010 with a 5.3 and all I have done is a air intake I am more than likely not going to do anything else

I want to get rid of the afm is my main goal and I dont want to use range.

I had a range unit and had issues I know alot of people love them but I want to stay away

any recommendations

Diablo, used it with my 2010 Avalanche, and now my 2013.  Disables the AFM, and has other programming options.  There are a few guys that can also write custom programs for your Avalanche.

Here is one place where you can purchase it.

Ditto about the Diablo.
