Thank you for your reply KeYa.
Does it make any changes in exhaust sound also when upshifting in higher revs please?
I am from the EU, I have a stock F30 20i B48. I installed only M Performance exhaust that gave me nice farts when upshifting around 5000 rpm that I have lost after updating only EGS, DME and FEM GW ECU units (I-step update has not been done).
