I have a 2011 GMC sierra 1500 with the 5.3 I was wandering if anyone has any suggestions on what gas programmer is best for the truck in economy, performance, and towing

Black Bear Performance is definitely the way to go for a custom tune.

 

The Diablosport tuners seem to be popular also but they come with one size fits all tunes.

 

If you really want the truck to drive better and increase performance, you are much better off with a true custom tune.
