2006 is the year to have in a Duramax. First year of the big horsepower, and last year for the good mileage and lack of particulate filter bullshit. The next one I get will be a 2006 for sure.
And my 2005 gets around 19 mpg at 60 mph and around 16.5 at 70 on the 90 horsepower setting with a Bullydog Triple Dog Downloader.
