    Do you have a boost gauge?

    That is not normal boost. If your car is stock and your gauge never exceeds 7 psi take the car to the dealer and have them find the problem.

    Normally you should be running about 12psi.

    How can you tell what boost you're getting (i.e., how do you know it's 5-7psi)?

    really? the 06 stock was set at 11.6. i didn't know they changed it for 07. I hit around 14 with stage 1 reflash

    OP: if you want to safely increase boost get some type of engine mgt. Cobb AccessPort etc...

    DO NOT slap on a boost controler and call it a day...you are only asking for problems by doing so.

    Oh...Welcome to the Club! there are tons of guys/gals tha know their stuff on this forum and much more friendlier then nasty sock.

    I haven't heard that one!


    I thought it was 11.6 to. and I think it was there for a while but the more I drove it the higher the peak boost would start to get, and it kept slowing increasing, now my new peak is at 13.92psi. hmmmmmm.

    that's strange. my boost gauge tells me different. but keep in mind that it's peek boost i'm talking about , but it's around 13.5 on an average pull.
    Still, seems high for stock.

    Yeah, but to the OP, we all agree 5-7psi is wacked.

    If you are using the Subie boost gauge, are you converting units correctly? Try this out:
