Hey guys. So I’ve been riding on my current tune a while which I have massively enjoyed. But I’ve been looking over the AFRs wondering whether I have the AFR to provide the most power. I’ve been reading every thread I could and there seems to be no straight answer. Seen it all from low 12s to mid 13s.

What is the best Afr under stage 1 conditions for power? Mid range rpm is currently in the upper 12, and upper rpms to redline are about 12.5, obviously at 100kpa. Thoughts?

Doubt you will ever get a straight answer, however 12.5-13.5 is the most common. Leaning a hair to the leaner side will produce a hair more as long as the timing is spot on. 13 would be a good safe number.
