leak tested mine up to 22psi and my greddy didnt leak at all...def get rid of that piece of crap BOV. The stock one will serve you much better.

 

I just did a boost leak test this weekend. I have a stock DV valve and it began to leak at 8psi and got worse up to 20psi!!!

I just ordered an MR DV valve. Best deal I found was 109 shipped from gruppe-s.

 

MR BOV waste if you plan to turn up the boost or upgrade your turbo...buy a Tial or Greddy. My Friend used one a MR with his GT35r and it kept opening under pressure.

 

Running the boost level in your sig the JDM MR or IX BOV will be your best friend up to about 25lbs. Forge makes a DV that will hold more if needed

 

If you can find a greddy type-S i would say (and many others) thats the best BOV for our cars. You do the single spring mod and its acts basically just like stock but will hold whatever boost you put to it. Not to mention sounds really nice with an intake on. I think i got mine from EvoMoto for $210 shipped over a year ago. They have discontunued the Type-S but you should still be able to find them around.
