OK to better explain what happened I took pictures of the scangauge .. even video, but I am trying to load that up now. Anyhow, if there is no other explanation then there is a dramatic drag on your vehicle when wind is blowing above 5 mph, average wind speed for this area is 7-10 mph, plus the days when it is gusty as hell at over 12 mph.
Here are the scangauge readings once I got home .. Everything including settings are correct, so who knows ...
While driving @ 40 mph
