PPK typically adds 20-25 wheel horsepower and 25-30 wheel torque--or a bit more than the claimed 20hp/32tq crank number. Of course, I have never seen any BMW literature that specifies these numbers as crank horsepower so perhaps the factory is just stating the numbers they had from dyno development. Because dynos show right in that range consistently.
