Because of my confusion regarding the readout as stated before, the 230km/h was speedo readout, and if you calculate you can see that it is approx 3% to high compared to the GPS, that means a "true" speed of 223km/h.
But, I will test that tomorrow when I'm going home.
Probably the best way to check it is to "lock" the 3:rd and floor it, and see when 4:th comes in.
One thing is worrying, theese speeds seems to kill winter tires in that way that the cord brakes...
So, maybe I reconsider ....
