thanks Dave! Personally, I can live without wot during shifts, I always drive it like a manual anyway. I know it would be hard to determine but the reason i asked about internal differences was because I know of a few 05 5eat's that hold the power of a 20'g when in manual mode doing dyno pulls. Wasn't sure if the power handling capability of the 05-06 and 07-09 were different. (I.E. clutch disc sizes, etc).
