ABT-Sportsline tune

Hi! I bought S6 c6 and found this kind of stickers at both ecus. Does this mean that they are modified with their tune?

There is a better then not chance that would be the thing. You should be able to look in vag com and see if they’ve been flashed. ABT wasn’t a real impressive offering for this. So it’s not going to be expected to be JHM power but it’s probably better than stock.
