    but that thing makes you run rich and is actually hurting your car.
    You do get flames and a cool sound, but it actually makes your car slower by slowing down the turbo in between shifts. Try looking into a recirculating one if you really wanna keep the sound

    The afterfire (not backfire) is caused by the combination of the catless exhaust and aftermarket BOV. This will happen from time to time. You can keep the aftermarket valve; it's not going to hurt your car any, provided it isn't leaking and is setup properly.

    It swings on the rich side of the spectrum, but nothing to be concerned over. As long as it's a quality valve (read: doesn't leak), and is properly setup/maintained.

    If he purchased the aftermarket valve as a "performance upgrade" then he wasted his money, and would probably be better off selling it and spending the money elsewhere. If he purchased the valve because he likes the way it sounds, then he should keep the valve (given the two criteria mentioned above are met).

    i know everyone says you should stick with the stock bov, but i didnt. I was wondering where i can buy a blanking plate for a tubosmart dual port bov, so i can run it recirc. I tried their website but they only gave me part numbers.

    Give 'em a call... you have a top-o-da-line part, I am sure they will support it...

    mmm, coffee... and a header tank...




    edit: you can also trace the plate off the valve body, then machine/drill it yourself... just gasket it, and it should support way more pressure than it will ever see... I'm a die-hard DIYer though...

    Yep, nothing to worry about.

    Turn off the code and drive normally. If this happens a lot, you'll need to look into a custom tune and/or an EWG setup

    there are some BOV's that are supposedly not as harmful as others but i still think they're a waste of money & for most applications, completely useless.

    ^ +1 read that FAQ.

    BOV's are mostly for people who run an FMIC setup where the standard piping doesn't allow for the use of the stock unit.
    The reason they're not that awesome is because they make you run rich between shifts if they are the VTA (vent to atmosphere) type.

    I know how you feel though, they sound cool, and you see some of them for sale and you think. "oh cool an upgrade!"
    Just remember, our cars are build real well, not like chebbys or Fords. So upgrading isn't necessary all the time.

    God.........why couldn't this thread been the one to disappear instead of the Bugeye Mafia.

    The rich condition is not that big of a deal. And it has nothing to do with running a FMIC. The problem lies with the valve design and the fact that the end user needs to tune it/set it up for it to work properly. Full VAT's are much more problematic than the 50/50. In my opinion the best valves out there are hands down the APS 50/50, Worx DS2 fully adjustable and the Turbo XS hybrid.
