So what just apply one fold or several more and the leak is gone or does it get more complicated than that.

Im running a EBC Greddy profec spec II, its cool to use the low to high boost function in just a second, then car feels like a different monster.

oops, I said 30R didn't I... I have an HTA 35R, sorry about that I had someone else's car on my brain

like Tsurugi-san said, it might leak there as do many other bov's but it's a quick fix IF you have that problem. Teflon tape is about .99 cents at any auto store so don't let that scare you away.

^^^No prob that sounds like a 1,2,3 process, yea I thought that was weird "30r" but I thought it might have been your previous turbo.

APS twin vent is great. It holds boost and has stock like driveability.

If staying on the stock ecu, then do the APS twin vent.. if going to a standalone.. you can't go wrong with Tial. Good luck

you shoud go with greddy type s or rs, theres no need to be going over 26-28 psi if your car is built and tuned right, you wont need the boost to reach your goals, your motor will do that for you.

Well It looks like we have a winner, APS twin vent, I have not heard any of you say anything bad about this BOV or anyone ever on this forum for that matter and I knew it was a really good choice before I made this thread. Bottom line it sounds like this will be a great choice, lets see:

1.Holds over 30psi and holds boost to redline pretty well- Awesome
2.No or nearly no flutter at low or high rpms - very important
3.No bad reviews all positive feedback

If I'm missing anything please tell me. Thanks for all the help

16g - 24psi to 30psi(racegas) - turbosmart then APS twin vent

I always had luck with the Turbosmart BOV, it holds tons of boost. Did you adjust it? It took me over a day of adjusting before I got the right spring stiffness. Also you have to lube it every couple of months or it gets stuck. Before you toss it out give it a chance, it's a great valve.
