SAFC tuning

[HaLo]

Ok! Here is my current setup:
S13 Stock ECU
370CC injector
S13 MAF
11psi on a S15 Turbo
Apex-i BOV

How do i compensate for the blow off valve on the SAFC?

Now, this summer, I'll be running the above except:
555cc Injectors
300ZX MAFS
14psi daily
20psi track

Now, I know that under sensor type, I put 6 in, 2 out. But where do I start my fine tuning? At what correction (14 or 20 psi)? At what would be your rpms points (NE)?

Thanks a lot.
