I'll post the other videos I'm uploading right now.
i need to see AFRs @ wide open throttle @ redline to make an evaluation, for idle what your seeing is bang on :-)

@ WOT you want 11.3.11.8ish for a nice safe fantastic running car with lots of safety margin.......

anything under 11 is too rich, anythink over 12.5 is imo to lean... our engine do make good power in the 12s but i like the leway mid 11s gives you.
