The Cusco center diff is completely open isnt it? Just with a 35:65 torque split. So the rear wheels are going to want to go faster than the front on a dyno.

I know with my DCCD box Sean has it locked on the dyno. So the front wheel speed will match the rear wheel speed.

Yeah I always though the hub dynos controlled the wheels at a fixed speed or slowly ramped it up, constantly measuring torque. So if they want to tune some load cells at say 4000rpm, you set the speed and even if you floor it, the wheels won't go any faster and the engine sits at 4000 rpm.
