AirDog is an amazing addition to my 2009 Volvo VNL D13. Noticed immediately the throttle response is great! The throttle response is as good as it gets. My fuel mileage hasn’t come up much, but hoping that will improve over time. I need to learn how the flow route works on that. The engine idle is smooth and it’s noticeably quieter. I’m wanting to buy the heater that goes along with it. I’m extremely happy that I made this purchase of the AirDog and would do it again. Thank you.
