mapped it stage 1 with milltek, and noticed that it over revs slightly, when on motorway and revs are around 3-4000 rpm ish. put your foot down and revs go up and dip back down before going up again. noticed it before the map as not as much and also noted it on my mates s3 too... replaced the coil pack the otherday.. feels almost like clutch slip. but it aint that.... any ideas?
