Has anyone explored this parameter and the different values? Appreciate any advice / experience. Here are the power levels:Performance Classes

KL = Lowest level
UL = Lower level
ML = Middle level
OL = Upper Level (current setting on my 30d)
TL = Top Level
SL = Super Level


***** Update ******

Changed the setting from OL to TL and there is a noticeable increase in the sound being generated by the external speaker when in Sport mode.
Can this be coded using the BimmerCode in Expert Mode?
