Re: A Thought About MPG
I would blame a combination of emmissions equipment and poor factory tuning. Try a catback and see if you don't pick up a few by cutting some of your pumping losses.
Edit: is it the supercharged version? If so, I don't know how you're getting that good of mileage...
96 Powerstroke: 6637, downpipe to dump exhaust, 140v IDM and a shift kit.
84 Honda Sabre V65 1100: pipes, jet kit and new tires. Faster than I think I'll ever need.
