I was wondering about the kind of tune that you guys are using with race gas, 100-116 octane. Usually we all use the 11.5:1 air/fuel ratio, or something close to that for 93-94 octane, so what ratio is safe for high octane fuel? 12.5 to 1? higher? Im curius because my focus has always been with 93-94 octane gas. Thanks in advance

nobody ?????????

 

are you guys serious? nobody uses race gas?lol

 

FWIW, here is an AFR graph from my Vishnu stage 1+ custom tune on 100 octane:

 

I use about 12.5:1 on race fuel. About 11.8-12:1 on stret gas.
