Old review, interesting notes...

Looking for seat bushings, came across this, go figure they had some good insight, nice writeup...

And crazily enough, that really is the tip of the iceberg. Audi's contention that the V8 maintains its 415 pound-feet maximum torque across such a wide rev range means that the company has had to severely limit boost. Indeed, the engine controller regulates both boost and ignition timing to make sure that the engine doesn't put out too much torque. Otherwise, one suspects the transmission would frag itself.

...and the following paragraph:

In fact, the RS6's one performance weakness comes from a sense of Audi's normally robust five-speed autobox feeling challenged to accurately put all that twist to the pavement. Get on the gas quickly after having backed off and the subsequent downshift is anything but smooth. Those thinking of hot-rodding an RS6 with an aftermarket "chip" will have to be mindful of the tranny's limitations.
