How do I know my car's max charging rate for Supercharging?

[Nilatac]

Wow the most I've seen on my second hand 75d is 60kw. I reckon it must have seen a lot of supercharging in the past.

I have a second-hand p85d with the same issue (got it 2 days ago), what did you do about it: to be expected to be this low or your got tesla to investigate/fix it? Thank you
