    I have been searching the history. I found lots of MPG discussions about tire size affect, etc..but what if I have changed my gears to the 4.88 and I have 35" tires. So in my caveman thinking, I'm wondering if the gears affect the mileage shown as well as the MPG? I have the bullydog gt Platinum programmer which allows me to adjust mileage and fuel economy.. but am trying to figure out how much to adjust it. It doesn't allow my to increase the tire size in the computer.
