CFM56

Hi All

Would really appreciate some help. Our A320's have CFM5-5B4/P engines. Can anyone tell me me what the /P means, I know its a bit nerdy but humour me!!

The TCDS say in Note 14:
CFM56-5B4/P = Same as CFM56-5B4, except for redesigned high pressure compressor, high pressure turbine, and low pressure turbine.
