In my mind the answer comes down to finding a balance between performance and reliability...

Naturally, the same question applies to almost any modern turbo engine. Since I’m not a mechanic, and even less so a tuning specialist, but my own rule of thumb would be to avoid anything with after market tuning, no matter whether still existing or removed, if on the market for any second hand high performance car. Try and establish an understanding of previous owner/s as individuals - I’m a firm believer that it’s not how BMW built the engine (tolerances between similar engines) but how we as users have used them.
How do you tell a tune has been on a vehicle prior to purchasing the vehicle; especially, in the light that the previous owner -- knowingly -- as a lessee -- reverted the vehicle back to stock prior to his/her lease end term?

Indeed concerning to me as well!! I think as part of the PPI, I am going to try to find an inspection company that includes a Blackstone Oil Report along with its findings/due diligence. That's the only way to find prior engine abuse AFAIK. That, and a launch control engagement count -- [btw -- if anyone knows how to look that up, slide up into my DM] possibly?

Are you swaying away from the M6 now? Headed towards possibly a RS7?! Or E53 bc of MBUX?
