I also have a 2017 build 530i B48. M Sport
Mine is brand new, was compliance plated July 19. So still under warranty.
It’s just clicked over 2200 Km’s
I have asked around for performance mods. Have had many V8 modded Holdens.
I decided to do an ECU remap. Have been told it’s more custom to your actual engine.
Put it in yesterday for a retune but they have found out it has a different ECU that the program can’t read. Someone in Italy is writing a program to read the ECU.
Anyway, the place I’m getting it done at said they can do intakes, better cooling systems, retune, exhaust and a list of other stuff to the car.

There is a couple of places in Sydney that can do it.
