I had an 03 six speed 4x4 cummins with a Smarty that got 19 around town an 22 highway an that was turned up on level 7 an that was driving the piss out of it

My old 06 mega cab automatic cummins got 25mph highway being friendly to it on interstate and it had 120hp injectors, 30% bigger cp3, 66mm turbo and lots of other goodies.

2005 sterling with 450 Detroit (I think) gets 5.7-6.1 depending on the day

13-14 in the city and 16-18 highway depending how I drive. 04 6.0 power stroke with exhaust and extreme street tune

'05 duramax LLY EC/Allison/4x4 ~17-18 mixed driving empty, ~13-14 towing my car on a open trailer ~#4500. I have a mild tow tune in it from my PPE xcellerator programer. Biggest thing with duramax's to help milage is to keep your rpms down at 2K or less on the highway which ='s about 65-70 mph with the stock tire size. Over 2K rpms it starts drinking fuel.

6.0L 4wd CCSB, best i can get is 12mpg, doesnt matter whose tune is in it, Gearhead, ID, Spartan, canned, etc.

Banginggears mine was low and didn't matter highway or city until my FICM went out and after that went back up to normal. I'm running a swamps 58v FICM with the PHP flash. If you want some info on how to get the mileage up pm me your number I fought with this 6.0 for a year to get it to pickup
