220 has been the highest I've been able to get to (2012 AT in manual mode) with 8+ hours on non-stop spirited driving through the hill country of central TX. Once it reaches that, it soon drops back down to 190-200 on the straightaways @ lower rpms. The stock OC in the '12s works just fine. Like others have said, start to worry when you get up to 260+. Other than that, have fun with your car!
