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.

I have seen great fuel mileage improvements as my prior average fuel consumption was in the mid 6’s. My last two tanks were 7.2 and 7.9, which is the most I have ever gotten!
