That seems strange to me since Jeff has 3.15 gears and he was less than 2 tenths faster on E85 in better DA compared to my run on 93. You guys might be right but I am not sure you have enough data to make that call. I can throw the 3.15 in my car and see how it goes but I am going to see what the 3.73 will do first.3.73s in auto s550s are notorious for slowing the car down, 3.31 gears are absolutely best
