Most cars read over what you’re going past a certain speed limit. It’s a safety thing.
I was going 80mph in my Volkswagen CC rline and my radar went off and said I was going 75mph.
With the bimmercode app, you can turn this off to read the true mph

Yeah mine reads 3-4 mph faster...
It's pretty annoying but I got over it...
My Silverado reads 100% accurate according to my gps speedo...so not all car manufacturers have this built in "Safety"...

This is easily fixed with coding...

Speedometer Display correct Speed (not 3⁄4 mph faster)This removes the speed adjustment so actual speed is displayed on instrument cluster


Main→Instrument Cluster (DKOMBI2) + [Expert]→3000 ANZENGE_KONFIGURATION→BC_V_KORREKTUR→ ohne_korrecktur (i.e. without correction)

There is a "your speed' radar speed sign/display near my area and the Supra's speed is exactly the speed that was displayed on the unit. I've driven past there in my other cars and all of them were exactly the speed displayed, so it appears my Supra's speedo is as accurate as my other cars.

Think all German cars are. Audi is the same
