    We don't mean to scare you, we just need to know the full story. If that is indeed the full mod list, a catless uppipe should be in your near future for safety reasons.

    Just get your codes read, and let us know the results. It might be in your best interest to pick up a Tactrix cable soon.

    front mount intercooler

    i believe thats everything, performance wise
    It should really be running a larger fuel pump with the larger injectors. I've never heard of the tuner, but I'd really question somebody at a dealer tuning it since it's rare for a dealer to have a dyno.

    I do mean to scare you a bit because you really need to know about the tune with a car with that list of mods or you could blow your motor. It's especially concerning that the car is throwing codes and not running perfectly. Personally, if I were you, I wouldn't drive that car until you know exactly what the tune is. If you have to drive it, I'd drive it like a 100 year old grandma and keep the revs below 2500 and never try and hit boost or floor it at all until you can get it checked out.

    So you didn't get any info at all about the tune other than the person who did it? Zero zip nada nothing?

    I hadn't heard of MSPT either, but apparently it's a performance division of a Subaru dealership there. There are a couple of reviews from people online, so I won't question the tune so much. There are some things I would do differently with your modification list just to give you some more room (fuel pump as suggested above), but let's focus on your immediate problem rather than finding out every little detail of your tune. If you trust the guy who owned it before you, you have reciepts, and you're good with it, that's all that matters really. Though I would suggest a checkup with the tuner soon if you can swing it.

    Don't post again asking about your issue until you have the code (P####) to provide.

    Code- P0171 (system to lean bank 1), from what ive researched many people of had this code, theres dozens of other threads ive come across with same issue. not neccesarily a big problem, but can get pricy because there is so many little things it could be. heres the list ive come up with

    -MAF sensor (clean it)
    -intake leak
    -vaccum hose leak (may consider because there is a tiny bit of turbo stutter)
    -plugs
    -fuel filter
    -front A/F sensor (O2)

    pretty sure there is other minor things to check but thats all i got off the top of my head....let me know if youve got any input. thanks for all your help so far. im ganna start simple obviously and then get more into it. thanks again

    Definitely check for leaks in both intake tract and the vaccuum system. If your car is detecting leaner conditions via the O2 sensor than it expects from the readings from the MAF, it will add more and more fuel until it gets to its desired targets. So, it stands to reason that you're seeing some decreased fuel economy here. As you said, start with the easy and least expensive stuff first.
