Calibration error exists when road speed does not match indicated speed..
There’s no way of telling whether the speedo is correctly calibrated until you run it in the car....
The reason that both speedos read the same with different indicated TPMs is that they are adjusted differently.
The TPMs quoted on the speedo face may bear absolutely no relationship to the actual TPMs depending on the gearbox fittings..
