How many people are running 91 octane in their boosted setups and what A/F are you running on 91?

Ive searched, but the combination of 91 octane / air - fuel ratio and / or A/F ratio isnt friendly with Honda-techs search engine. Any input would be great. Thanks

 

ttt anyone?

 

timing is more of a factor then fueling i beleive
its easier to control detonation with timing then it is with fuel

11.5-12:1 is avg
