Interfere with firmware to adjust motor speed?

[pdhung197]

I have an issue with my Move Hub that the motors A and B have difference speed. As you see in the video, motor A a bit slower than motor B.
I don't know if is there any solution to use pybrick to interfere with firmware to adjust motor speed?

If you use Pybricks instead of the official LEGO firmware, then the motors should work better.

(We can't provide support for the LEGO firmware - you would have to talk to LEGO customer support about it.)
