If you go FI I would still add an air oil cooler, probably a 24 row, the stock one is nice for street driving when NA and some light track but that is it. I ran the OEM radiator for a year in Texas without many issues, traffic I saw my water temps could get up so I decided to upgrade and it helped a lot. I would do the fan adjust in Uprev first and see how the car is, many have had success with adjusting when the fans kick on and speed through tuning without needing to upgrade the radiator.
