I see a lot of pros quoting numbers similar to this. I used to run 11.5AFR with about 22* timing; the leaner tune with less timing seems to be making a LOT more power. Which makes perfect sense to me.[quote]


When you say you're targeting 12.3:1 AFR would that be on 94 oct pump?

This is becoming a great thread guys. Super helpful to me and I'll be referring back to it often I'd say.
