This guy is selling his S8 and it apparently dyno’d at 480 whp with the flaps removed after a custom remap.
Here’s the video: https://www.youtube.com/watch?v=kFbj66fHAK4
and here’s the dyno sheet: http://www.3dink.co.uk/audis8/dyno.jpg
Guess that means our cars can’t be that far behind…? I need to get a dyno session done anyway I think.
