LLY/LBZ mileage with a 3500 chassis?

[Diesel Wanna Be]

What are you guys seeing with hand calculated mileage for a 1-ton dually crew cab with it in stock form? What about with a mileage tune via EFI Live?

I know that the 2500 series are getting anywhere from 18-22 depending on the tune and equipment. Just wondering how much worse the 3500s are due to extra weight and rotating mass.

TIA!

Everyone told me this was the place to come for information... 13 views in two days???

Nobody keeps track of mileage with their 1-tons?

Anyone? Bueller.... Bueller...

I only tow with mine so I can tell you that pulling a 40' loaded trailer it get right at 10 mpg.
