In naturally aspirated cars, you typically tune to a ratio of about 13.5:1 during WOT.
15:1 is lean.* Time to figure out why.

15.1:1 isn't too bad, certainly not too lean to dyno. is that A/F at normal or WOT? if that's at normal, then it would be a problem, because all cars run leaner at WOT, unless you have an aftermarket ECU that allows for seperate WOT maps

So if the stoichiometric ratio is an intended constant regardless of most variables, then how can I reach this effectively?
