I completely agree with all you said, but I think you might have meant to say that Speed Density calibration is calculating mass air flow from MAP/RPM/displacement? I'd completely agree that a properly calibrated MAF sensor is not only precise, but also provides compensation/insurance against all kinds of other variables that affect air mass (intake manifold heat, intake valve temp, spark variation due to knock retard, etc).

Thanks for catch - corrected my faux pas!

I think most OEM's are using similar strategies for forced induction - it allows much better 'picture' of engine operation and more hooks for control.

OEM software and calibrations calculate injector tip temperature, intake valve temp and many, many other parameters that impact engine operation - all this results in more precise control (and closer operation to the edge while maintaining safe operation).
