I just found out about these and was wondering if anyone else has tried one? Apparently it can work in 3 modes. A 50/50 split recirculating half the air and venting the rest, full vent to atmo, or full recirc. Anyone else?

Why?
There are a ton of re-circulation bov's out there that don't cost anywhere near $175.

If you are running the Stock ECU don't vent to atmosphere, the computer accounts for all that air going back into the accordion.
If you vent to atmosphere it throws off all the fueling calculations.

Standalone, do whatever you like.

What is your goal for choosing this style BOV?

I figured it would be a "one and done" solution. Run it in full recirc mode while I'm on stock ecu, full atmo when I go standalone.

And about the price, I found a $20 off brand that does the same thing after I posted this lol.

Why do you want to vent to atmosphere running standalone?

Sound mainly. I thought diverter/ recirc valves didn't live long at high (20 or so) boost levels. My over all goal for my car is 600rwhp, 600rrtq.

It’s just a vent valve no matter which why you use it. They don’t go bad. Stock ones can go bad but the after markets rarely do.

For standalone or a map based system it is just simpleier to vent it.
