Here's the catch/disclaimer, I did have my snowboard on top of my yakima rack. Mod-wise, I just have the rear-sway + front-strut bar combo, aFe Pro Dry s drop-in filter. I suspect that the snowboard is causing my MPG to drop.
At 65 mph my rpm's are about 2.5k-2.6k, at 75mph they are slightly under/around 3.0k; does that seem normal? And if so, who are these people claiming at 3.0k rpm's they can get 29-30mpg? Anyways the last factor I could see throwing my numbers off is the presence of hill, when the computer would shift down aggressively to maintain cruise-speed. (Or maybe I just "forgot" about segments where I was jumping out of cruise-control to pass people for fun...)
