You can't compare the new 6.0's with the old 6.0's. These new ones have the active management that automatically shuts off 4 cylinders when you don't need the power. Thats how you are getting such better gas mileage.

Time for a tune up in my opinion. Run some sea foam through it, change the spark plugs & wires, Oil, Clean your MAF sensor etc. etc.Bagged 06 Silverado Crew Cab.

I hit 18.7 mpg driving 60 on the highway after refueling last week. Average highway is 15-16 and around town is 13, thats driving very conservative of course. I do drop to 10-11 driving like a 16 yr old when my 6 yr old son says "go faster or that guy wants to race" lol
Only mod is a drop in k&n filter. no more tonneau cover. I do make sure tires are at 60 psi front and 70 back per my manual.
