Chevy Duramax Turbo Diesel

Originally posted by techntrek Don't upgrade to Windows 10. Starting with 7 they started introducing "big brother" technology, adding more with 8, and now 10 basically sends everything you do back to Momma. I have a programmer for my truck and I could turn AFM off, I should some time to see what effect it has on the mpg. I don't like it when it kicks in, it has a noticeable vibration. I understand that has been solved with the newer version of the system. I will be interested to see how that aluminum body holds up for the F-150. I have heard good things about the Eco-Boost.

Thanks for the tip on Windows 10. If you do try to run without AFM, I, for one, would be interested in the results. The only comparison that I can make is to a prior 1992 GMC Sierra - 5.7L (350ci)TBI, 4speedOD, 3.42 rear end. If I behaved myself, I could get 20mpg on the highway. Usually more in the 18-19 range. I've only had the present truck on the highway for one short drive, without towing. I got about 21mpg. It is the 5.3L, 6speed and 3.42 rear gears.

I need to correct myself on a prior comment. In reading some articles, one (Motor Trend - maybe?) said of the turbo diesel - it is "a GM motor produced in Thailand". So, maybe not "sourced", as I stated. It further said that the motor has been available in the international market (non-USA) for a number of years.

Also, it appears, in order to get the turbo diesel, one must purchase one of the higher end models (think LT crew cab package, or better). It looks as though one will need to take roughly 40K with them to get one. The only incentive I could find is 3.9 financing. In checking inventory within 20 miles (of me), there were no turbo diesels and not many gasoline versions on the lots (about half of those were the 4cyl variation).
