Trying to get my Type R dialed in for my FD....currently, I am getting some compressor surge, so I assumed to soften it up some. I went ahead and took the valve off and went to adjust it softer, and it is almost as soft as it can get.....I mean like 1-2 rotations away from having no pressure. So my question is what can I do about this, or what could be causing this?
The top nipple is where I have my pressure source line running and the bottom nipple is open to atmosphere. Now I am running a 60-1 at around 12psi....I was using an Apex'i Twin Chamber, worked great, no problems....now with the Type R, it is just not reacting properly. Is it just too much BOV for a 12psi single? I have a TIAL sitting in my garage, but have to get around to haivng the flanges adapted and wekded on to make it work, which I will do if I have to....but I was jus curious about trying to get the one I have on the car to work properly.
Any help would be appreciated.

I had an Apex'i Twin Chamber and M2 Large before and it worked fine.....then switched to a Greddy FMIC and Type R....and I just can't get it dialed in properly.
I thought about trying it at around half in to see how it would react, but I didn't want to adversely effect my car any more....would tightening it up some help it open faster?

Which spring do you have in it???
The GReddy Type-R BOV comes standard with the "stiff" spring.
You need to order the softer "std." spring and swap them out.
The stiff spring doesn't budge under 20psi!!!
BTW, using the bottom / angled fitting doesn't do jack **** to it's operation, unless you're running closed-loop.
That fitting just "leaks" into the BOV outlet.
Blow into it and you can hear it venting into the BOV outlet.
