Custom tuning makes it all go away... you max out the values in the torque cells which on HP is like 131000 lb ft and it's gone forever. Just loaded a "custom" tune in my buddies 14 from an online guy... truck shifted hard and that was about it... still a slug. Yeah I opened up the file and looked it over... I think I could honestly do better and I am just a hack lol.

I own a 2011 2500 Crew Cab and a 2006 Yukon XL 2500 with 6.0s in them. Both have 3.73s and neither are slouches. I test drove a 2015 before I bought my 2011 and the 2015 was not inspiring to say the least. At work we have a 2017 Quigley van with the 6.0l and it too is not inspiring. Not sure what the deal is with the inconsistencies of the engines.

My Yukon pulls 15+mpg with a pretty good 50/50 mix of city and highway. Just picked up the truck and decided to look at the DIC for mileage on the way back from a party and on the interstate at 75 I watched it climb from 14.2 to 14.5 in 40 miles. I'll take it on a trip soon and check mileage by hand then. I'll be happy with 15, my 2003 1500 x-cab 5.3 gets a little over 16 (150,000 on it) with 3.73s and all highway miles on a full tank.
