Forgive me, but I am unfamiliar with your terminology. What do you mean by "harder lock up in S5 and S6"?
I think I found someone in my neck of the woods who is doing the SMG Euro tune. I am running stock so I am wondering if under your opinion it is worth while to get the tune? If I understand correctly, the tune may go through the life of the clutch much faster than the regular US programing.
