Purchased Champ II in June 2020 and installed myself on 2002 T-800 Kenworth with Cat C15 engine. Have noticed better throttle response, especially once the fuel got lower in the tanks – it remains constant. After 6 months, I have seen 2/10 of a gallon increase or roughly 4% increase in fuel mileage. I also noticed quite an improvement in power. I’ve told a few of my friends about it and since I took so long to see just how much it changed, they tend to believe me. I’m satisfied.
