Yes, I know there are various compensations for the MFI system - which btw, often get discarded/disabled in effort to make them run better.
The thing is, we are talking open loop vs closed-loop feedback. Don't get me wrong, as a Mechanical affectionado/egr the MFI system is very cool. ...but do note, that injection systems will bring more and more precision, as the open-loop gets closed.
