    Do you have your tuning graphs? If there are peaks or valleys at the shift points after the final tune, then you might want to have it re-tuned...it also depends on the factors used during the tune. Overall, it shouldn't have an impact and you should be able to run fine on it. My suggestion would be to contact your tuner and ask them.

    Theoretically, worst case scenario is that you had periods of rich A/F's during your shifting, and if the tuner compensated for this (doubtful, but possible), then you could now have periods of lean A/F during shifting. It also depends on your EMS method. Cobb AP? Chipped? Piggybacks tend allow the stock ECU settings free reign for compensation on fluctuations in A/F, so if this is your case, you'll be fine. If not, again, contact your tuner to be sure, and be sure to ask him questions along these lines.

    I wouldn't worry too much though.

    Ya take off the Greddy BOV and put the stocker back on.

    The Greddy RS can be set up to VTA (vent to the atmosphere) or recirculate. How did you set it up?

    B/c VTA is bad for your engine and will throw off your AFR. Regardless the BOV has practicially no benefit to you so go back to stock (unless your pushing major boost/20PSI+).

    Also I suggest you carefully read these threads:

    1) http://www.clubwrx.net/forums/engine...foramtion.html

    2) "The BIG BOV thread" (Where all bov question threads get merged)

    Next time please do some research before you buy parts.

    The answer is already given above. However, you might want to consider something:

    Makers spent a tremendous amount of time, money, and resources to design products that are capable of withstanding reasonable use for at least the warranty period (if not, the maker takes on the expense -- so the incentive is there to makes stuff last at least that long; longer still if you consider that a reputation is difficult to obtain and easy to lose and no manufacturer wants to lose theirs). Why use unauthorized parts on a brand-new car, particularly if they address absolutely no need whatsoever and yield absolutely no benefit whatsoever?

    Doesn't it make more sense to use authentic Subaru parts when needed, and leave well enough alone when not?

    The 09 is a great car. Keep meticulous maintenance records, follow the book to the letter and I'd expect you to be thrilled with it.

    If y ou want to keep using it you are gonna have to tighten up the spring inside. It is staying open at idle and that is causing the car to die.

    ^correct, just wut he said, but if u tighten it too much then ur bov is gonna have a fludder sound and that will cause compressor surge which is not good, so when u hear that just loosen the screw up just a bit until the flutter is gone

    then keep it, put it on later, and deal with the problems that arise, at that time.

    Well since BOV's casuse all kinds of problems...do they make BPV's that can support higher boost levels?! If they do then hell yeah I am gonna sell it and when that time comes I will just get a better BPV...makes the most sense!!

    What hybrid BOV did you have? And did it run better when you put the stocker back on? I have the GFB hybrid and haven't had any problems for the past 4-5 months but I'm all kinds of worried about leaks now that I'm doing all this reading...

    I had the turbo xs hybrid on my WRX...the main reason I took it off was because of all the reading I was doing...plus...I kind of grew out of the pssst sound...I thought I liked it from hearing it on other cars..but I realized that was when I was in highschool....I'm not a big fan of it anymore! Plus I am pretty sure it wasn't adjusted right since I just put it on and didnt make any adjustments...ha..I honestly can't tell if it runs better with or without though...
