How much better is the 14-15 6.2 vs the old one

I probably seem like I am complaining about my truck but I'm not.
I just think the 6.2, 6 speed, 3.73 would be the best performance combo.
For aggressive street driving, not wot from a dead stop, you are always a couple of gears away from where you would want to be, no biggie.
I have been working on my tune and have been making some improvements as well.

I have a 15 6.2 with the 8speed. CC reg. bed. I really don't know what some of you guys are talking about. I've owned fast LS powered cars, and driven all types of large trucks. For what it is the 6.2 8 speed is an awesome powertrain. It's not just mileage, the performance is fantastic for a truck, bone stock. 13.77 1/4mi with a 6000 pound race wieght is not low performance by any stretch off the showroom floor. I hit 27.7 MGP on a long roadtrip with the 6.2. My mostly in traffic lifetime is 16.7 and will improve with a few mods. (Truck is new still) It seems to shift much better with the TC off to me. No, it's not going to have diesel like towing performance, and that should not be expected & it's not a vette. But for somewhere in between, is pretty impressive to me. I guess I don't know anything. Not starting an internet fight. I really like mine, & in coming months the tuning will be figured out & what mods work. The overall rifinement is nice, I don't know what is better on the market right now(subjective I know). I could have bought any truck, & choose specifically the 6.2 8 speed after much research, and am not dissapointed one bit.

Reading your comment, I'd like to add I was very impressed with the towing performance. I towed 7000 lbs from SC/GA area and went up through the Appalachian mountains and it pulled like a boss. I'll be honest, I was in a hurry and I pulled often at 70-80 and although it worked, I wouldn't say it struggled whatsoever. In fact I was impressed with the power, especially when I would pass people going up hills. It's a bad *** package for a truck imo!
My buddy had a his '15 F-150 with a 3.5 ecoboost at the track with me and I tore him up. Nice truck, but I'm glad I went with the GM. My .02 or .03....

Dammit I going to have to upgrade pretty quick. I swore I wouldn't after getting it paid off a couple years ago but I guess the trucks at a good point to. It sure has been nice not having to work on stuff to keep it running just mods here and there.
Everyone seems to really like the new 6.2/8 spd.

I owned the previous 07 denali SUV tuned by justin for almost 7 years and I can say it was faster than the 15 6 speed denali which is tuned by Charlie
Wheatley,the difference I felt is in take may be because of the awd,now I am planning to get Lt kooks 1 7/8 and retune again.
