That sounds correct. During non boost conditions the ECU samples (from O2 sens) the mix and adjusts, that's why you see the readings bouncing around from about .2 to .7 When the readings go steady the fuel is being added according to the air entering the engine. Yes, you need a richer mix under boost.
