My 2019 arrived and within a month I installed the AR Stage 1 pipes and Stealth air cleaner. No ECU adjustment was necessary and it is essentially the same thing you will have, much more open pipes and an air cleaner with the Stinger in the venturi of a more open air cleaner.
I have been told by someone who did it that installing the Stage 2 cams will not upset the ECU either! Amazing. Pretty tolerable ECU.
2019 M3W Sold and is now in Las Vegas enjoying the showgirls :-)
