Has anyone else noticed that the speed limiter in the CM2350 cals does not really do anything?

I set D2021 from 164 to 250 and the truck still won't go faster than 164 kph.

I maxed out all 3: D2021, D2022 and D2023. Truck still won't go faster than 164 kph.

I am guessing there's a cal in the background that I haven't found yet that's getting in the way. Does anyone have a hint or .cax file?
