    OH so if I add a BOV then it would consume more fuel, damn thats not a good idea, the gas prices are kinda high.

    it was the driver farting coz the clutch was too stiff.

    just kidding

    yeah, that's BOV. its used to get attention and unwanted engine problems down the line. the kid inside me wants me to have one coz of the "pppssshhh". but i'd rather be more mature and logical about it.

    besides, if i really want a cool noise, a loud exhaust should amplify the boxer sound. lol.

    if i were you, i'd spend the money somewhere else... like a bottle of hennessy.

    Well I hope it is a Recirculating BOV as if it is venting to the atmosphere that is very bad for the engine unless tuned for.

    As for adjusting it...in my experience (I have a perrin Recirculating BOV) I just play around with it harder or softer and see which way the engine likes it best (keeping a close eye on my A/F ratio and how the car feels) and go from there.

    But, if you have no experience with it I suggest taking it to a tuner or going back to the stock BPV.

    Read this: http://www.clubwrx.net/forums/engine...ov-thread.html

    Also, are you running any form of engine management? and what part of FL are you at?

    How loud is the noise?...b/c most likely its VTA (venting to the Atmosphere) and that is bad. Whats the Model number of your Greddy BOV (does it have that metal tube that recirculates back?)

    Does it look like this: GReddy Type RS Recirculating BOV Kit for 02-07 WRX & 04-09 STi, WRX Blow off Valve from JSC Speed

    You should get some EM before any serious mods such as Downpipe or Uppipe.

    I live in Cooper City/Ft. Lauderdale.

    Also, I noticed from your profile you have a Cold Air Intake/CAI. That is also bad with out tuning/EM as it will cause you to run lean. You are probably running way lean and that can and will hurt your engine. You either need to get tuned for the CAI and BOV or better yet put back on the stock airbox and BPV.

    WRXs are not like a POS civic which you can just put on a CAI and run with it. Due to the compression and sensitivity of our turbo engines the A/F can really be thrown off by a VTA BOV and CAIs.

    PLEASE READ: Engine Performance FAQ [[[READ ME]]]
