i thinkI might have proof of airtabs working for me. I drive about89km each direction to work everyday. Last week my tank to tank was 36.28mpg that pretty stock as I removed my airdam and grill block. This weeki added 6 airtabs that I made and mounted on magnetic sheets. My mileage for this week was 37.69mpg. I will remove them again for next week and see what happens. My testing its not strict but I set the cruise control for the same speed every day andI take the exact same route to and from work. Most variables should even out in the course of the week anyway.
