I understand what is being done, But I don't know the purpose of it.
If someone doesn't mind explaining I would like to know why someone would do this? What is the benefit of doing this?

u can run it from the intake manifold port, but not from the lower charge pipe port, that one only sees boost not vacuum, which u need to open the bpv. if u do go straight from the intake manifold, u will have to put a hose on the solenoid from the bpv port to the bottom port on the solenoid, if u just leave the bpv port open when u switch gears or whatever, ull have a vacuum leak at that port, and while in boost, u will have a boost leak at that port, the way the solenoid works is when ur in boost, the top port on the solenoid that is connected to lower cp is open pushing boost on the bpv holding it closed, when u shift or whatever, that port closes and the bottom one opens providing vacuum to the bpv, opening it. that should help you. if u have a zzp lower pipe u can just remove the vacuum nipple and put a plug in, then u can just completely remove all vac lines from solenoid and just plug the bpv straight into intake manifold and nothing else.

I had same issue, but just going straight to im, didn't help, the problem is the spring in the bov is too stiff. I put a lighter spring, it was better but not enough, so I ran both bpv and bov, that worked, thinking about it, what would work the best is putting a really light spring, like a 4 psi or something into the bov, then running off the solenoid, otherwise if ud run off the im manifold with a light spring like that the bov is open at idle.

o2 sensor code. lol u gotta read my post where im talking about why I don't like to delete codes in the tune. I think u misunderstood and thought I ment when the engine light comes on I don't delete the code, I ment I don't like deleting the codes from the tune. like rear o2, cause if there is a problem u will still get symptoms but no code, so u wont know whats wrong.
