I installed the system on my 8.3 Cummins as soon as I got it [November 2020] – had an order to transport 174 car loads of BMWs, so I needed to hit the road. My truck has performed flawlessly, easier cold starting. Runs great and contrary to earlier assumption is definitely getting better fuel mileage. My 4th qtr IFTA return will tell the tale. Should have bought an AirDog years ago! Thanks
