To check if your BPV is leaking, all you really gotta log is Vac/Boost. If you're on stock tune, it should peak to about 15-16psi then fall down to about 11-12psi by redline. You should start with a blue spring/no shim. If you got more mods add the 2 shims in there. If you run more boost than stock, use the red.
Log KR, Actual AFR as well just for giggles.
