Is your 2021 M5c faster after you installed the JB4 or did it stay about the same? BTW 10.9 stock is pretty fast! |

There is no flash tune available on 2021 right now, and jb4 will not remove check engine either.
You either have wait until the ecu is cracked so you can flash, or take off downpipes. You will not get any further help from the forum, as there is no solution available as of now. |

Seems even Piggys are being affected by this new updated software. Time to look into the M8c and stay stock |
