I usually drive about 125,000 miles annually and use about 29,761 gallons of fuel. After the AirDog was installed, my fuel use dropped to 24,038 gallons! My mpg pulling my Bull Rack before putting the AirDog on was 4.1-4.3, now I get 5.2 and have seen up to 5.7 with no wind and 70-75,000 lbs. Plus, my manifold pressure went from 27 to 33 psi and my exhaust temps dropped from 825 down to 650. The truck puts out less smoke and idles much smoother.
