08 ccsb 4x4 bone stock. Just got 18.99 mpg for 250 miles at 77mph. A dpf and tune is an almost guarantee 2 mpg, but it is a deff void on your warranty. As soon as mine is up I'm going efi and exhaust.

Thats the mpg I get as well.
Delete all that stupid emission crap! Get EFI live and straight pipe it. I had the PPE tuner first, which is the best handheld tuner you can get, however there is nothing better than the custom EFI live tunes! I can go from a 30hp tow tune to a 200hp race tune with the switch of a dial! Plus with EFI live you can add a turbo brake feature which is amazing
