I've never noticed that, and I have no idea what would cause it. You are taking about when you run it richer you see the airmass increase? Increase by how much?

I believe once you start getting richer by about .8 lambda with ethanol and other highly oxygenated fuels I think it starts displacing air. But obviously this is going the other way and would be decreasing airmass.
