B: avg mpg 19.6
A: avg mpg 18.8
B: avg mpg 19.4
A: avg mpg 18.8
So it looks like a lackluster improvement of ~.7 mpg or ~4%
The ambient temp was 10* and there was a NW wind at 10-15 mph. The road was East to West.
So I don't think the test is really all that valuable. I'll be interested to see how my mileage looks over time.
I'll take some more pics and maybe you all can let me know if you see any areas that may need improvement. I was really hoping to get 10 - 20% improvement.
(EDIT: testing speed of 55 mph)

Ten degrees with a 10 to 15 mile per hour cross wind, I guess 4% increase in fuel efficiency isn't all that bad after all.
