I had to adjust my mind to cope with all the extra power when I came from my stage two tuned C5 RS 6, to the stage two tuned C6 RS 6... I'm now having to do it all over again.
On the old filters and map, it made 715.1PS and 934NM, with version 2 MRC filters, (developed for the stage three 860BHP+ cars.) and a map tweak it went to 754.3PS and 1021NM, Doug reckons it will do more on a cooler engine, but it had been on the dyno having the map adjusted for around two hours and it was 28 degrees outside.
If your map is a few years old (one of the sub 1000nm maps) they've updated it since then, get it booked in... The difference is >>>
Edit: The 1021NM now comes in @ 3823 RPM vs 934 @ 5572 on the old map.
