Well, there have been no announcements so far from either Vishnu, Burger Tuning or Cobb, specific for 1M.
Please only post announcements and releases, not assumptions that some tuner might probably have a tune in the future
Cobb isn't even ready with a tune for all existing N54 platforms (1, 3, Z4, X1, X3; i/iS ; AT/MT etc) , and they refuse to give a timing for when they will be, let alone they will have a tune for the 1M soon.
Also, no N54 engine has been released so far with an M button that tweaks its settings. So tuners cannot 'copy/paste' from iS to M verson of N54 platform.
Anyway, didn't want to start this thread to discuss N54 tuning, only to gather a list of announced/released tunings available specific for 1M.
