6G74 65mm TB - Smoothing out the inside lip?

Just looking at the 65mm 6G74 throttle body, it has a lip that seems somewhat unnecessary on one side of it.
Does anyone know if it hinders airflow and whether it is best smoothed out?

Leave it.. she'll be right. Engineers woulda put it there for a reason.

Or something.

Thanks Daniel.

I know that one of RPW's mod is to smooth it out, but much like what you said I feel that Mitsubishi would've spent more time in R&D and there must be some reason for it being there

I really dont think it would make any difference in an NA car.
