I totally agree about the low grade fuel.
We are very fortunate to have an abundance of your equivalent of 93-94AKI here in Australia. Non Ethanol 98RON.
To me it looks as though the tune works both ways. It's a performance tune AND works better with higher quality fuel.
Looking at the S2 figures with 91AKI, the car still perfumed considerably better than stock, Stage 1 & 91, so there's your performance enhancement. Although it has yet to be proven (a formality) the same S2 with 93/94AKI (98RON) should (read will) perform with improved results, based on S1 figures.
So the BMS N20 piggyback tune is both a performance and fuel grade enhancement tune. The best of both worlds!!
Then we have even better results with the ER cat free down pipe - albeit pretty much illegal on the street. So we need yet another tune classification for replacement parts.
I look forward to S2.
