Ok thanks. Just realised I butchered the original post. It should have read 91 octane for map 1, and 93 for map 2.
What I was really trying to deduce was, is our 98/99 RON over here good enough for Map 2? And if I happen across a petrol station that doesn't have 99RON, and only has 95, would I be able to use map 1, or should I revert to stock?
