Success!!!

Finally got it running like the bosch valve. It did require me to use the pink spring, the blue spring was just way too soft and it wouldn't close when it needed to under light load. Bit weird that you're running more boost and had to use a softer spring than I did... Maybe it's cause you're on an upgraded block? Or due to where your BPV is located in the air to air setup? Not sure.

I popped in the pink spring, set it about 2 turns harder than the softest position. This was a little bit too tight, as the valve wasn't opening at idle. So I softened it a little more and eventually got it damn close to perfect. Took it out for a drive after cleaning exhaust tips / bumper, and no more nasty exhaust soot going everywhere. Will have to grab a datalog with cipher but seems like a/f is in check again!

My current set up is the pink spring with no spacers, about 1/2 turn harder than fully soft on the cap. Maybe the green spring would be our ideal choice to have a bit more room for adjustment.

BOLIO, what I would recommend if you want to try it is buying the valve and adjusting it with the pink spring first, if for some reason you need it to be softer like topgunz, you can either trim the pink a bit or buy the blue or green one, but honestly I didn't need the blue one at all. Green might have been nice. Would have resulted in much less of a headache if I started with pink instead of blue

So so sooo happy that it is running great again
