Hi all,

As the title states, I am currently in the process of purchasing a 2018 F87 N55 with 55k KM.

It was listed with a “custom exhaust”, and nothing else. Upon test driving the vehicle I immediately noticed intake noises followed by the classic pops and bangs from the exhaust. Nothing CRAZY, but enough to tell me the car is either on a stage 1 or stage 2 Bm3 or MHD tune. After the test drive, I requested to have the car hoisted, and (obviously) found the catless DP, not entirely sure on chargepipe however. In the engine bay was a CTS intake.

The dealer does not have a list of mods which would make the process a little easier lol.

I am 20 and this would be my first BMW M car, so I’m not worried about the modifications that I would have done myself within the first 3 months anyways lol.

So I guess my question(s) are;

1. How can I find out which exact tune is on the car?

2. Will I be able to override the current tune with another if I purchase a license? Or will the original license need to be removed with some type of passkey from the original owner?

3. Is it more likely that the car is running on 91 or 93?

Just to finish, I have probably made it obvious that I am new to the tuning world of BMW’s, so I may have left out some details, please let me know if additional info is needed!
