If you're staying NA on the stock getrag but want more pickup I would say 3.73 is a good ratio without making the lower gears totally useless. If you're going FI then you actually want a much taller diff to stay in boost for a long time, like a 3.15. __________________ ![](image.php?s=b02a6fd6c5c70567e28f4021bf3bac16&u=9846&type=sigpic&dateline=1373440016) -Alex |
