Rcf would be a downgrade.
If you're hard pressed on getting it tuned via bm3/mhd then go for the 2020. Unless you want to dish out 2g on femto unlock on the 21.
Lol "car enthusiasts" yet not knowing damn well that CTR was upgraded to the gills for track whereas the Supra was on stock everything and also the 19-20 varient model prior to bump.
Backfired real quick mate.
