I've read around a bit and I see quite a few people not satisfied with the greddy type-s bov. It seems like %90 of the threads out there are all about which one sounds better, but imo i could care less. I just want a bov that performs best out of the two. I plan on running upper 25-30 psi on a pte 50 trim and I'm a little nervous that my crushed 1g wont be able to keep up. But after reading about the type-s's idk if that will either. I know I could just get a tial and be set, but I've read a few things saying 1gs can hold up to 30 psi. I was just looking to see how much boost your running on a 1g bov (crushed or uncrushed) or a type-s.
 
I would get a tial for runnning that kind of boost, just so you know that it would be able to flow enough air out when ever you need it to. The type-s is adjustable so you can increase the pressure it will hold. I'm only running 15psi right now on mine and have had no problems so far.
 
I"v had the type S for about a year now and havent had a problem with it. If your looking to push that much boost why wouldnt you look into getting the greddy type r? But like said before for that much boost I would look into getting a tail BOV.
 
I've had my type-s for over 4 years now.
never had a single problem with it.
you have to understand that for every person complaining about a product, there are probably 10 people perfectly happy with the same product.

Well I've had my Greddy Type-S for about 4 years now as well, but I just started running higher boost levels. At around 23 or 24 psi the BOV will start to leak open. And the problem with tightening them or adjusting them is that it will give you bov flutter/surge at low boost. I say go with a tial which I plan to do pretty soon.
 
I have an Apex`i Twin Chamber which is supposedly capable of 29.4lbs, but soon I will be replacing it with a Tial or Syncronic just because I don't trust it. I also do not trust any of the Greddy valves for that amount of boost.
