    Not hitting target boost stock

    I have a stock 13 wrx and lately I have been noticing that my spt gauge has only been peaking at 10 and holding steady. Tonight when I did a wot pull my car peaked at 10 then dropped to 9, but it was 4 degrees out. Is it normal for boost to be lower when it's freezing out. And isn't stock peak 14.5 then taper down to 12.5. That's what my car used to hit.

    Cold air supposedly makes your car run better.

    Boost would not be going down in the cold. One thing that cold can cause though it loose connections. I would take a look around in your engine bay and make sure nothing has slipped loose. I would start with the intercooler as the connections here have been known to come loose.

    Did you "feel" the loss in power or only realize it by looking at the boost gauge?

    When I was running a stock tune, mine would peak around 12 or so in the winter. From what I understand, the OEM tune has some sort of compensation on it during colder months, to keep it from creating too much power... Then again, what I have read on the internet may be entirely wrong, since it is the internet after all.

    Seems odd that they can hit 13 psi and you cant. Have you always been underboosting or is this just a new issue?

    Also, on a side note, if you ever have anyone from the dealer take your car out for WOT pulls, go with them.
