While wanting a recirculated valve? That goes back to my original question.

I picked up the GFB Stealth 50/50. So I guess its pretty much a 2 in 1 deal.
Im pretty much all stock atm besides a K&N typhoon intake

Just had problems with my hks ssqv with stalling, But just yesterday I changed it up to a TurboXS RFL, and now I have Zero problems, I know its an atmosphere BOV but I seem to be running better than ever for some reason. And the sound is awesome IMO....

Sold separately? I dunno. I ordered my old HKS with the recirc fitting for my '08 WRX. I might try to get the flange for the STi once I start pushing more boost, at which point I'll be selling the fitting for the '08 WRX. They do sell the flange separately for the 02-07 WRX and 04+STi for sure, and you can find it on eBay. I'll likely have to get some special hose to run it recirculating, because the WRX setup is different for that too.

How is it possible to tune for an "off throttle" condition? To tune for a BOV you would have to have a lean condition at redline in anticipation of the car going rich when you let off. You can't tune "in anticipation" anywhere else in the rev range safely (to be clear, it wouldn't be safe at redline either). I'm just saying that I don't understand how it could be tuned for an atmospheric BOV any other way. I would love to hear in what way they could compensate for it.

The only real risks you run with that rich condition is harm to your A/F (front O2) sensor, (rear) O2 sensor, and any cats you might have. Other than that, you get popping from the exhaust, which can be embarrassing (you can shift really fast and never experience the popping though). Keep in mind, if you foul the A/F sensor, you could then potentially damage the motor, but I doubt that would happen with the brief amount of time the car will be rich. It takes a large amount of fuel running rich to foul the sensor, as I understand.

I don't like the fact that it has an 8" tube connecting it. I found a 07' STi HKS BOV flange, I might buy and see if it fits. I want it to sit right on the intercooler.
