Forget anything you read about normal port injection A/F ratios...our engines run direct injection that fully atomizes fuel droplets and creates a pure homogeneous mixture in the cylinder which facilitates much tighter control of mixture and means we can tune our cars to the lean limit and in some cases beyond perfect stoichiometric (14.7) safely.
