Pass, I don't know what you're modelling to say if there should be much of a change: I'd also not know if you showed me it as I don't really do wings & air flow.
Re the residuals, have a look at the wake region too. Too many new users fall into the trap of only looking at y+ and one or two numerical outputs: you need to study the whole solution to see what's going on.
