Waiting to talk to you for a week, registering for this forum is a nightmare.
Here M2 is a $100K car, $50K used for a first generation M2. You're about to drop your 15 years of savings on this car then luckily you learn of all this BS (and the crank hub, got to love that "superior" german engineering). Which no paid shill "journalist" has ever mentioned even though it's present since N54 cars, and nobody on youtube is ever talking about so they don't look stupid with their compromised manual clout mobile in front of the people they are "influencing".
If I had the car here are the people that I would talk to in my part of the globe, they have a reputation for being some of the best BMW tuners:
Gelashvili Performance (Mr. George Gelashvili)
-
https://www.geptuned.com
- based in Georgia, they do remote tuning when not touring USA
THP Solutions (Mr. Zic)
-
http://thp.solutions/
- based in Croatia, I don't think they remote tune, but worth inquiring about the issue in general
