It will be nice to compile all found settings in sorted list of hyperlinks.

Is it off by a lot? What do you use to get accurate speed?

it reads 6% - 8 % higher than actual speed according to iPhone Speed app and Waze.

I wonder if you get the same speed as the Speedo with Track Precision App.

I can't compare my Speedo with TPA until Spring arrives up here!

I noticed my speedo is about 2-3km/h higher as compared to the speed signs in school zone signs and construction speed zone signs, although I have no idea how accurate they are.

I'm only guessing, but speedo is probably calibrated to the expected wheel diameter & wheel speed sensor. If you change the wheel diameter, the speedo will probably adjust accordingly.

There is a setting you can make to put the exact rollout of the wheel in mm in PIWIS, I'd try that.

In my case this is with the OEM wheels and tire sizes, in fact as delivered, it has always been that way.

My GT4 and Waze are pretty dead on.

What do you know. The speed calibration is different between US and Canadian cars. I checked two Canadian cars and they have the same as yours. Then I checked mine and a GT4 and they show 100%. That is the best way to avoid a ticket in Canada

My guess would be the conversion from kmh to mph
