Does anyone know the power disruption on an A6 2.7t 2003

Do you mean overall efficiency loss or are you talking about the torque interrupt during shifts?

Since it’s 4 wheel drive is the back getting more power or is the front

Ah, see what you are asking now.
Under accelerating load with no slip, the torque should be applied more to the rear than the front because of the weight transfer.
It’s the weight and the co-efficient of friction tyre to surface that determines how much torque can be transfered.
The Torsen differential is mechanically clever, it notices slip and re-directs the other other way.
