When I was looking for a tuner, the only one that really came up was 5 Star tuning. I ended up buying the SCT 7015 from them with 3 tunes, economy, daily tow, and performance, all with the 87 octane.
The biggest change was the shifting.. I doubt it makes anymore power if any.. but it does shift so much better, it holds the gears just alittle longer which is really nice that it doesnt shift into 6th and then back into 5th all the time.
One benefit is that you can adjust tire size and tpms sensors and a few other things.

There is a thread in here about someone turboing a 6.2(didn't work out), but he did a base dyno runs before turboing, stock and with his 5 star performance tune. It equaled all of 5 hp, I'm not ******* 5 star, they get great reviews on here and I will eventually have one. But the performance you will feel come from shift strategies and really waking up the lazy throttle by wire. This has been my experience on 3 vehicles with throttle by wire and two different tuners.

You'll defiantly see an improvement with a tuner. I wasnt impressed with my 2016 until i added one. Now it feels "right"...if that makes sense.

I remember that and the pics from the thread and some of the dyno results, it looked like a beast under the hood. If I recall right their were some issues that didnt get worked out and I think the Op of that truck and thread wasnt too pleased about it.
Too bad though it looked awesome 
EDIT: Found the thread where the truck with the turbos in it was for those who are curious:

The outright power increase of tuners isn't great but these trucks "feel" much better with a tuner. I drive both a 3.73 and 4.30 geared company 6.2s. The 3.73 geared truck is "quicker". Really don't know why that is?

I think the real difference in "feel" in the tuned trucks is changes in shift points, and the throttle position isn't limited at low rpm's like in the factory "tune".
Just from my reading on the forums here, don't have a tuner myself.

I have the SCT X4 with 5star tunes. It really woke my truck up. I run the 87 towing tune every day and when towing my small flat bed trailer with my SXS. I run the 91 towing tune when towing my toy hauler (10,000lbs +). I lose about 1mpg with the 87 tune unloaded, but it's about the same milage as stock while towing. With the 91 tune the milage is about the same as stock but you can really tell a difference in power when towing. If used for towing I would get the 5star towing tunes and maybe the 87 fuel milage tune and forget any of the performance tunes. I got the 91 performance tune and needs work as it didn't run right, transmission shift points seem to be off.

It seems to me that you can accomplish most of what the tuner does by using manual shifting mode. Most agree that tuners don't influence mpg and many have pointed out that they are not happy with the new shifting points of some tunes. If you want to improve performance while towing or with larger tires, going to the 4.30 gears is a better investment.
