Audi S4 (b6) what's quickest tiptronic mode, manual or sport

[p1tse]

So Manual mode is the one left to Drive, which has 6 forward gears

S mode I though just sharpens the throttle; but actually when using the paddles in S there is only 5 forward gears?

Sport mode simply changes the automatic shift software.

Using the paddles in either automatic mode overrides this.

Neither offers any more power/performance assuming same gear and throttle opening.
