No idea, but there should be many people present who have
performance mods on their cars which should be glad to talk.
>2) Should I bring my wife and newborn or leave them home??
Unless your wife is into Audi talk and wandering around the paddock
of a race track, I would suggest the home option.

On some models this fitting is used to route vacum/boost pressure to
the top side of the wastegate which effectively lowers/raises the boost
control spring pressure. On the S4, it isn't used in this manner so it just
sits at atmospheric pressure.

I think you are referring to the tube which is used to measure CO.

As far as I know there is no Bentley manual for the S4 available.
