I definitely want to get k-pro in a few weeks. I kinda fear I am running lean. I made a drive today from Auburn, AL to Charlotte, NC and I filled up when I left. I made it all the way into the city of Charlotte and my gas light went on. I had made it 365 miles, i switched between windows down and up with the a/c on. I just replaced my primary o2 sensor last week and I have definitely noticed a major gain in mileage.
