2020 Peterbilt 389 with Paccar MX13 Engine
I first heard about the AirDog line of products on the XM Radio Road Dog Trucking show and purchased an AirDog in February 2021. I have noticed an improvement in throttle response and a lot smoother engine idle. I have also noticed an increase in fuel mileage, which I track using Kevin Rutherford’s fuel gauges.
