that was what I had read about the nitrogen. I wouldnt have thought about it except someone on a 350 forum I believe had written about similar issues and the switch had apparently cured it. I have noticed a little better mileage though. I gave the tires another once over for nails just in case { i thought checking the tires for nails and the like was sorta a given} and right now I'm working and dont have my guage with. I'll check the pressure tomorrow once I get home.
