I've unlocked the “speed limiter” in “absolute limits” up to 300, but it seems to plateau around 200. Did I do something wrong, or is there still a limiter that hasn't been unlocked yet? Or is the top speed of a stock BK around 200?

Stock 3MPS BK speed limit is at 250kmph or something, that is about 270kmph on the dash. 200kmph is nothing for these cars, stock or tuned, they will get there pretty fast.
Next time you push it to that speed also log that run and let's see what actually happens, most likely your car developed a small issue over time. Use this dashboard config preset: https://www.dropbox.com/scl/fi/55qyxbqs ... mnqqb&dl=0 - download it and then go to Dashboard -> Presets -> import and load.

I’d like to share two stories here—one good and one embarrassing. The good part is that the car kept accelerating even after it exceeded 200 km/h. The embarrassing part is that I forgot this car has a 6-speed manual transmission, so I might not have shifted past 5th gear. That’s probably why the top speed plateaued at 200 km/h.

That is absolutely fine, a 3MPS BK reaches 200kmph in 5th at about 6000rpm which is the sweet spot on these engines for peak power.
The problem with your car is that it makes probably around 180-190bhp in a good day. Either the EBCS is fitted backwards, or it is stuck closed.
