just to chime in again. I rarely put the transmission in sport, however for grins I drove around yesterday with both the engine and transmission in sport, OMG the care was a beast. had way too much fun which is why I remember not to do that too often
on the bimmercode front, if you go to the website ( I know how archaic) they allow you to see what can be coded for your specific car. I did that to plan out my coding before I jumped in ( yes I am an accountant by training)
anyway good luck and enjoy it has been a long time since I was so thoroughly pleased with my car
