Take the gearing recommendations with a gain of salt, they are only suggested starting points for further experimentation.
23/81 looks to be way over geared for a 6.5T motor, I would even try something like 17/81. The fact that it doesn't run hot is not surprising in a light 2X4 buggy.
To reduce cogging you can raise the starting power parameter but watch the temperatures as it can cause the motor to run a little hotter.
In theory sensorless controllers work better with lower turn motors than with higher turn motors.
The latest software versions have a torque limiting feature. I haven't tried it myself but some people have recommended it.
