Thought I would bring back an old post to see how the numbers are looking this year for you Duramax owners. And to hell with the poll that's old information!

I'm seeing roughly 16-18 mpg per tank on average with speeds of 70-80 mph and a 70 mile round trip daily. Thats with the mods in my sig and a real rough EFI Live tune. Plus I hammer on it quite a bit. :thumbs:
