You can use TuneECU to unlock the top end power of the RS model, if your R is a 2020 or newer. The new R and RS are the exact same motor, same tune, etc... The R just has restrictions on the top end using the ride by wire settings, so that when you give it 100% throttle, it delivers a lot less in the upper RPM. I made a video on my channel of how you can get rid of that restriction, easily. Keep all the low end and mid range grunt you currently have, but add 8hp or so up top like the RS has.
