Right, so why do many here say they are "making the turbo louder"?

Because they have no understanding of what it is they are doing.

So what do you do with the hole that the hose was connected to? Put a plug in that too? I love the whoosh sound haha I might do this

Or too smart. The BPV is piped back into the intake so that air keeps your turbos spinning in case you are going to get back on the throttle. Venting it to atmosphere for the sound adds lag when you lift the throttle and then get back on it.

On this note, is the 3.5 in our trucks accounting for this in the fuel table as well? I ask as a subaru WRX I previously had used a recirc BOV and if you went atmospheric, the engine would actually slightly bog down due to the air being added back past the MAF so it was adding fuel thinking it would be having the extra air. I guess I am asking if this air is added back to the intake pre or post MAF?

Not a factor on the raptor.

No MAF on Raptor.

I’d like to know if this is fact. Can anyone else chime in?

That’s the whole point of recirculating the blow off.

Notice I said “anyone else” lol. You may be correct, i’d just like a consensus. Plenty of vehicles running VTA
