Not disagreeing with any of above.
The main point I was making was that for a given fuel flow, less RPM is going to mean more torque (since HP = torque * rpm).
Now, torque originates from the pressure in the cylinder, directly. So, as Drauk points out, lower RPM means more torque which means higher cylinder pressures.
I too reduce RPM from 2575 to 2500 after takeoff, for lower noise, once terrain clearance issues are out of the way. But this is almost incidental.
