    If you add an intake you must tune it.
    The scaling on the MAF will be off and cause engine damage.
    You should get a catted Downpipe and a Cobb AP or a pro tune.
    It will be a world of difference power and torque wise.

    That's what " YOU MUST TUNE IT" means in TownLine's post, yes.

    If you aren't tuned, your MAF scaling is off, your car is pulling in more air than it's used to, and doesnt know what to do with it.

    No problem, the tune itself isn't terribly expensive. You can get a flash from Torqued Performance for roughly $80, but you'll need either a Tactrix Cable (A.K.A "Opensource), or Cobb Accessport in order to apply the tune to your vehicle's ECU.

    That's a good price, but not really needed at your level of modification unless you just "want" it. They'll be able to squeeze out more power and fine tune everything to your specific car, though.

    What you're hearing isnt your car sucking in too much air. The sound you hear is due to going from a plastic intake with a silencer to a metal tube with no silencer. You can simply hear the air moving through the intake into the turbo now.

    Best bet don't install the intake yet.
    Get the downpipe Youll be glad you did.
    You can get them hear used for a good price.
    It doesn't make sense to pay for a Protune just for an intake.
    Do the downpipe tune to stage 2 and be done with it.
    Then your performance power and torque will be awesome.
    After that you can move on to other mods.

    If you truly believe that you are going to stop at an intake and catback then I would recommend you go for the pro tune, as they will give you a better tune (assuming they are a competent tuner) than an off the shelf map. However, if you are going to be adding more modifications in the future, it might be worth your while to get a COBB or tactrix cable and flash an off the shelf stage 1. $500/whack adds up on the pro-tune. You would pay not too much more than that for a COBB AP and the maps are free. They are very sellable used too, so it is not money down the drain. Either way, you should take the intake off and put the stock one back on until you decide what you are going to do. If you insist on not taking it off, you run the risk of doing damage. It's your car do with it what you like. You mentioned earlier that you don't want to damage the engine. Well we are telling you that by running an intake without a tune you are risking severe damage to your engine. Take that info and do what you want with it.
