All this talk about octane has got me wondering.
1. If you run JB+ at 100% would it be recommended to use 93+ octane instead of 91?
2. Is high octane gas wasted on JB+? I know on higher map settings for JB3 it's recommended you use high octane, but they have maps made for the octane. I guess the real question is, what octane is it worth going up to before I see minimal gains? Should I stick to using a 95 octane mix and below?
