Fine as long as you leave torque management in it.
Some smoked theirs early on with learning how to tune them. I have the transmission tuned as well, which has only been offered for a short time. Street and sport mode operate the same, but if I put it in track, it will shift better and at 6350-6400 vs the normal 6000-6100.
There is a guy in Florida who has over 300 1/4 passes on his and it runs 9.4-9.5 all day. The fastest auto car still runs a stock A8 as well.
