I can't quite believe you guys are also having to anticipate and tolerate these nannyish interferences. I thought only our EU noise regs were militating against burbles, but clearly not! The fact that they sneak such ECU adjustments through the back door (as they did with the M340i in Europe a couple of years ago) is also a bit galling. It's not like these cars sound like Jag F-types; deleting or even subduing the overrun crackles seems like overkill, whichever way you look at it.
