12-13 around town .. 14-15 highway - 04 CCSB 2500HD 6.0 4.10s 4L80E
Lies!! :anitoof:My DIC says 14.4!!! :rofl2: :rofl2:
Mine did ok when I had 285's on it. I would get anywhere from 13.5-14.5 in town and I got a best a 16.5 all highway once. I think I can get 15-15.5 in town now if im light on the skinny pedal. I havent done highway yet with the smalller tires though.i thought tunes really helped the 6.0's economy... but i guess if only if youre rolling stock tires?

I figured if I was willing to drive a little slower I would see quite an improvement.When you go over 2200 rpm in a 6.0 your economy goes down hill. I thought 13.5 at 85mph in a 1 ton truck was pretty good. I get about 16-17 at 70 mph.
