At this point not even sure I’m going to keep the car unless they can flash the DME

Just going to work hard, see if I turn a good profit in some investments this year and if so - M3 upgrade may make sense once I see how the AWD version comes out performing. Outside of that, this car is great all around. Still happy with my decision. Tunable or not (right now). |

Just read this whole thread. Now I’m sad. I bought a ‘21 M340i fresh off the boat, sight unseen 2 weeks ago. It’s awesome but I want a tune. Still nothing?
Thank God my spec had the staggered performance tires. Need to verify it will exceed 130. . |

That was me to all excited and bam couldn't flash tune. Don't worry you will be ok get the JB4, intake and downpipe then run an E30 mix and you will be good to go.

Another separate but related question - is it also true that the ‘21 exhaust is currently unavoidably less poppy than prior years due to the tune (irrespective of aftermarket exhaust systems). I have read pages and pages on this already but would like an authoritative answer if someone has it. Thanks. |

I dont know about aftermarket exhaust, but, my wifes 2019 X3 M40i is SIGNIFICANTLY louder and pops a lot more, including shift "burps" that Im jealous AF over (dont tell her) whereas my 2021 M340i makes VERY mild burbles and pops at low throttle/rpm. I wont lie, I covet the louder pops and bangs sometimes but then when I pull into the garage at work I'm thankful my car isnt that loud because our garage is under everyones office space and its sure to get you exiled from parking underground. Yin/Yang I guess. I have a love / hate relationship with this car

As Bhanana said, just unplug from the OBDII and set to Map 0, and you "should" be good. Yes, the 21' is more tame on the exhaust due to the recent software updates. I have the 21' w/MPE and it does pop every once in a while and burble at lower RPMs, but nothing like a 20'. I actually prefer that for the time being. Pops and burbles are cool and all, but only once you have that 130 lifted and won't get passed by a Civic in Mexico... |

That said...based on what I've come to understand:
That being said while I am lucky enough to be flashed tuned by Mission Performance because of my early 2020 build I would not be concerned about running a well designed Piggyback if that was currently my only option and switching to a flash when available. Just like I am not concerned about my well designed Dinan Springs. My 2-cents - other opinions may vary - hope it helps Quote:
