Most likely your car is already on latest iStep and if Dealer or you updates the software BM3 will know. If you encounter any issues you can email support@protuningfreaks.com

BMW F series (N55 / S55 / S63TU) Spark Plugs - What brand and which gap?

Should I replace the stock spark plugs with the NGK 97506 plugs in my S55 if I'm just planning on running a Stage 1 OTS or the OEM CS tune? Thanks!

U should be fine with stock plugs until you notice a misfire since you will be in STG1 or CS
