if so, then

but how do you know this? you've got your fuelling right on boost and you've got a 3.5% CO (is that at idle). but to say it's perfect means that you have optimised the ignition timing and fuelling for all load and speed sites - all without ever hearing what detonation sounds like.

it sounds to me that you have been supplied a good base map that runs and drives smoothly, but that does not meant that it is "all set up perfect"

i do hope to learn a lot when i get an S8, and i hope that you keep posting your experiences to help me.
