2011 Volvo VNL with D13
The AirDog with the Champ II provides the low-end torque that enabled me to properly re-ratio my rear-ends to leverage the engine’s downspeeding capability, giving me almost one mile per gallon fuel efficiency gain. My truck originally came from the factory at 500hp/1650 torque. Now, with the AirDog and Champ II, I have more of each, even with the engine set at 425hp/1550 torque plus re-ratioing the rears to 2.47. More low-end power, increased productivity, more enjoyable to drive, and one mile per gallon fuel savings. The AirDog was the key to putting this truck in its best form ever!
