I have 3:45 in mine - with the DCT - and it's been an okay mod IMO (for the street). I didn't go with a 3:62 due to the chance of over-rev on downshifts if the DCT ECU wasn't re-flashed. I think the stock DCT Diff ratio is a 3:15 so it was quite a decent change to go to the 3:45 given the 7 speed DCT box ratios. Just sayin'..
