Im pretty sure we have had this talk and unlike the MK5 which was setup as standard to run 98+ wasnt the MK6 setup to make peak power and efficiently on the simple 95 stuff?
I think there was a heated discussion, as i think I remember it too. IIRC Teutonic_Tamer was the one saying it and it makes sense to me * as the label in the petrol flap says similar on the EA888 engine
*Not the mk6 golf R, scirocco R, mk5 GTI or edition30/pirelli or seat cupra mk2, Cupra R mk2. (as it states reduced power in their handbooks on 95)
