I FINALLY convinced my dad to let me flash tune his 2018 S6, after reassuring him that we could easily return to the stock ECU tune, if anything went wrong under warranty.

Car in the video: 2018 C7.5 Audi S6, Prestige, 4.0T with the 7-Speed DSG.
-Stock everything, except the tune
-10,000 miles on the odometer
-Pirelli P Zero Summers

This is the Unitronic Stage 1+ Tune, and I highly recommend it:
