    It's called turbo lag. Have you had a turbo car before?

    hmm, 2 things:

    #1: you may be having turbo lag issues. If you're just going along at 2k, flooring the gas pedal will do almost nothing at first, until your turbo spools. Try the same up near 4k and you should instantly shoot off.

    #2: DBW. Your car is DBW, and thus, instead of a cable connecting your foot and the throttle, you have a complex algorithm. It sucks, especially when the algorithm is bad (as most find it stock). A reflash will give you better pedal feel (pedal input to engine output comparison)

    Make sure you're not looking for a throwing response if you're doing 35mph in 5th gear.

    Port and polish everything. Then get tuned.

    Yeah if you haven't had a turbo before then it takes some getting used to. Below 3k rpm it'll just bog down, but as you go over 3k rpm, it'll start to really build speed.

    Chudv23, what car did you drive prior to your 08 WRX?

    I went from a 2002 Civic Si to 11 WRX and the throttle response seems comparable to me.

    I agree that below 3,000 RPM the engine is tepid but I rather like that; I loaf around the neighborhood shifting at 2,500-3,000 keeping it comfortable and smooth (and probably saving fuel). Then when I have some room to run, I keep the RPM above 4,000 and it's a lot of fun.

    If done properly a P&P can really decrease turbo lag. At least that is what I have experienced.
