Something to note, on an aftermarket turbo, it's quite possible to end up with the worst of both worlds, where on light throttle, there isn't enough force to open the BOV so you get small reversion and driveability issues, and with the venting to atmosphere, it dumps a lot of fuel on shifts. Realistically, dumping to atmosphere under power isn't a major driveability issues, compared to the issues of stalling from reversion. If you're getting up the throttle, then putting the clutch in, say on a shift up, but then don't release the clutch, yes, the engine can and will stall, but, just drive around it, and that's easy, let the clutch out in the next gear and the car rolling will keep it all running / going.who wants a hard hit of throttle and then to just let the motor idle anyway? Main issue for driveability is blipping throttle and it wanting to stall, like when parking or trying to move in slow traffic. -

As in they quoted one price, you mentioned the exhaust, and they promptly added $200 on top? Interesting. -
Note that I'm not suggesting this is a great idea. Just saying that it is something that could be done to achieve a better outcome than the more shit ideas will provide. -
I'd try removing it, connecting hoses and see if that helps. Depending on specs, it could actually be restricting the flow(it also might be helping). -
Yes, that's a hybrid BOV. The adjustable spring load ones are about making teh pressure build up higher before venting, so you get a more agressive whoosh. That is not what I meant or what you want. By "restricting", I don't mean "keep it closed until the pressure is higher, then open it fully". I mean "open it as soon as it is required, but only have a small port area, so that the flow rate out of it is slowed down". The pressure will rise to be higher than a bigger ported BOV would provide, but it would do while it is venting. The idea is to slow down the rate at which the replacement eair is flowing past the AFM, to reduce the magnitude of the air flow signal peak, to reduce the amount of fuel that is added per revolution.
