another fix supposedly is the HKS EIDS does anyone know if that fixes it

I got it too but I cant really tell a difference in the sound except it more quieter.

I have the greddy type s...but im recirculating it....and its still really loud...almost as loud as the rfl....at the time i still had the stock air box though with the rfl...greddy is definityh a good blow off....no boost leak for me...
If you are truly going to VTA, then the SSQV is your only option to prevent stalling. Like it or not, it is the ONLY BOV that doesn't leak under vacuum (at idle). I learned this the hard way. I tried a Turbosmart (not the new evo-specific one), GFB, and Greddy before I kept the SSQV. My SSQV is crazy loud, sometimes even when I shift softly at 4000 rpm, and I'd rather it was quiet whn I wanted it to be.
Dual port is kind of a fake VTA, but great if you only want to hear it on hard shifts. The dual ports hit the recirc port a split second beofre the VTA port so that when they leak at idle, you don't stall. When you look closely, you'll see the VTA port is offset about 1/4" higher than the recirc port.
If you convert from MAF to MAP via an engine management system, it won't stall from VTA, even with leaking, but on the stock ecu, I promise it will with everything but an SSQV, I've been there.

Forge Motorsports VTA is the only way to go. It is what EvoM put in their project evo. Here is the write up they did. https://www.evolutionm.net/features/.../projectevo/22
I have one too, and it is awesome.

The only other thing I recommend is going 2-3 turns stiffer than the unit comes out of the box so it's not so loose when it does blow off. Aside from that, the idle does dip down pretty low once in a while, but only for a split second. I think I have stalled maybe once in the past 4 months but to be honest, that may have been before the SSQV, I don't remember. Hope that helps.
where's tial?
It's Tial or Forge. They're built to last and performance without too many peoplems.
Forge is plug in design, which i like for evo models. Welding mounts are pain in the a.
