500 CFM, what I wanted good to any RPM I would ever care about and good drivability (it runs and its drivability is like a Swiss watch compared to any of my other cars). I tuned it with an AFR meter. It is running around just a bit richer than ideal 14.7 (high 13's) at cruise and 11's at WOT (I think... I have slept since then). Oh and the last time it was at WOY was when I tuned it. :).
