I use the out-dated Greddy Type-S that's been sitting in my garage for 7+ years. I keep it in recirc mode and I think it holds boost better than the stock but that's just my opinion. I had it VTA when I first put it on and the Type-S sounds badass but it got kind of annoying lol. Daily driving plus "PSHHHH" every time I shift was getting old so I put it back to recirc mode where it operates much better. I would occasionally have a backfire when VTA also from it running too rich.
All in all, I suggest leaving it recirc. Healthier and less noise pollution.
