    New Here, New Car

    i recently bought a 2004 WRX and it has some mods.
    i'm really not sure what the purpose of them all is....any help would appreciated.

    It has a blow off valve...turboxs
    it has a megan racing turbo back exhaust
    Turboxs boost controller
    a FMIC...not sure what benefit this has especially
    air/fuel mix with a turboxs button thinging in the car next to my fog and cruise buttons, 0-9 not sure what benefit to this.
    air/fuel mix guage, pyrometer, and boost guage....

    I am also a newb, but sounds like you have a stage 3/possibly a stage 4 car. How many miles are on it? What kind of condition is the car in?

    The FMIC cools the air more efficiently than the stock top mount. Since colder air is denser, more air can be squeezed into your cylinders allowing for more combustion. But on the other hand, the piping associated with them may also cause more turbo lag.

    The blow off valve may cause your car to run rich, check the air fuel gauge.

    With those kind of mods the car must have some sort of engine management (hopefully) to keep things running smoothly.

    Good luck with it, sounds like it was modded pretty heavily, and as long as the previous owner didn't abuse it you should be fine. Is it auto or manual??
