So Ive got an avcr and a PFC and if I check the peak boosts on both they are completely different! Like, my AVCR shows about .89 bar, and the pfc shows .74. and I just want to know why that is, and if there is something I could look into to fix it.

 

It is a known error that the PFC commander displays slightly lower boost than you are hitting (it internally uses the correct value for the maps though). However, your discrepancy seems larger than normal...where are you getting the readings for the AVCR?
