I bought a 2018 S1 last year because they are so rare in the UK and immediately got an Abt tune to take it up to 310PS. Acceleration in 4th gear is absolutely insane as it now has so much torque. I managed to scare a TT RS the other day at least for a few seconds and I think people think it's a RS3 or RS4 when they see it coming towards them in their rear view mirrors on the motorway. I'm also growing to like the engine sound, and I'm glad mine doesn't have the comedy pops and bangs.
