As others have said, the PL/DPL deviation is NOT separately adjustable. It's a fixed percentage of the total deviation. It is very clean however, so even though it might measure rather high, it'll be quite inaudible. You'd have to add a resistor somewhere to lower just the PL level.
Make sure you measure and set the deviation with the PL turned on. Your total deviation should be set for 4.5 to 5.0 kHz; it will be less without PL. I haven't seen a spec on the PL/DPL deviation in any MSF manual either.
