I bought my 2018 340xi in March, both the initial factory flash and the current version, which addresses revving the shit out of the engine when cold, feel similar and have the same rev-hanging.
Which Software version/year is your tune based on?
I'm looking for a flash with must absolutely be undetectable, when I bring the car for service I will flash to stock but I cant have warranty voided.
I read the MP even with Mboot still bumps up flash counters and CVN
Not sure id that is still the case
