BOV upgrade on stock turbos? lost..help..
im wondering what a good BOV upgrade would be for the stock turbos. im getting a new FMIC setup instead of the stock one and was wondering what a good aftermarket bov would be for it considering theyre sequential turbos and theres different psi at times.. etc.. does the psi matter? im kinda confused.. help? thanks!

Any BOV is fine just make sure you have the flange for it to put it on the IC piping. The stock BOV worked fine for me till I went single turbo. I personally don't see the reason for upgrading if the stock one works fine.

Not completely true. The stock BOV has a fairly weak spring for the valve. Therefor, it closes much later than aftermarket BOV thus taking that much longer to build boost. It is possible to change the spring out of the stock BOV get that type of performance as Garfinkle does this mod, but aftermarket BOV's can provide better turbo response as well as "a difference noise". I will agree that the change isn't huge, but it is noticeable.

Your like a old man when it comes to this stuff. You have twin wastegates, you dont like them, and now you dont like a simple greddy BOV? You should put the stock catback on, bov on, and don't know what to tell you bout the 2 wastegates.
