i am planning on getting on the group buy for the pfc and i'm wondering how exactly it controls boost... currently my boost pattern is a little bit off, it's something like 10.5-7-9.5 with a downpipe as my only mod. my question is, should i try to fix my boost pattern so that it's 10-8-10 before installing the pfc or will i be able to fix it using the pfc? i don't really understand how it works and if someone could fill me in on how the pfc controls boost, i would really appreciate it. thanks.
