The figures quoted by BMW are for engine torque, which is measured with all accessories (e.g fuel pump) connected. Torque at the wheels will obviously be different in every gear.
I really don't know if the 330d and the 320d have different gearboxes. But what I do know is that a 330d with 500nm of torque shifts prefectly well.
If your chosen remapper (and I was referring to DMS in my post) are happy to tweak a manual 320d then it is probably because they are satisfied that the gearbox CAN take the extra torque.
I know that DMS will not remap a manual 330d for the same reason.
