Well, if ya lug it a little with a good pedal on the 100% setting, you get a nice plume.
I made the same trip home I do everyday, 77mph the whole way (61 miles), except a few bursts. I had the box set on the 1/2 setting, and I noticed a change in the overhead.
I have been at 16. 5 on the overhead on every trip (16. 7 hand average so far), every day for the last 2 weeks (1600 miles). Well, I filled-up and reset after I screwed around at lunch (when I put the box on).
The overhead was at 17. 7 tonight when I got home. Looks like this box may help out on all my highway driving.
I have a 250 mile trip tomorrow, I will see what that yeilds.
