Ok small test results went for a trip about 800 k strong wind against going and good wind against come home GRRRR
So it is hard to say what MPG improvements there will be in normal conditions , but I can say this even with traveling against wind MPG was improved over my last trip with out air-foil by about ¾ of a MPG even with the wind.
So I can say with confidence that there will be a improvement with MPG on normal days of a lot better mpg.
Wind noise in cab was substantially reduced LOVE That.
Bug splatter show a remarkable improvement and the surprising thing was the big sq part of TC right behind doors on truck was also mostly bug free as well and that is about 24” below air-foil add on.
The bugs that did get through were not so splatter and were very easy to clean off not like before as it toke a lot of hard work to remove bugs before.
Later in August will be taking a much longer trip and will have more test results.
