So yesterday I installed a AP bov. Everything is hooked up correctly and it is 100% recurc but for some reason it does nothing but flutters, and it doesnt matter at what throttle open or partial. I have done searches and have found nothing about this specific bov. Do I just need to loosen it up? I would put my stocker back on but i pressure tested it and it was leaking at like 20 or 21 pounds of boost. Please help thanks in advance

 

The stock one leaks or the AP one leaks? I had the AP one on and kept trying to get it not to flutter but never could. Maybe give them a call. When I went to get my car tuned the AP was leaking at 10 psi so the stock one is back on and I'm waiting for a Tial QR.

 

Sorry, i was my stock one that was leaking.... I messed with it again this morning and still couldn't get it to stop fluttering. I guess I am just going to crush my stock one. Thanks
