Really.. . A larger ratio usually has a big negative impact on your mileage. I have whatever the stock rearend is in my truck. I honestly don't know what it is off the top of my head without looking it up somewhere. I'll have to look more into the 4L80E tuning aspect, then. I know it uses a type of speed sensor that the 4L60E does not use.
