    Possibly. If I were you, I would still be wanting first to make sure I know what modifications are currently on the car since you aren't sure, and making sure that the car is appropriately tuned for them if they exist, and not driving if I can help it. Running lean is not good.

    I put it on economy tune and it runs alot better. The only code it throws now is p0171 bank 1 to lean. It runs better in this tune than it did with the stock tune.

    You really need to figure out what modifications are done to the car before you just keep throwing random tunes at it. Post up some pictures of the engine bay from different angles, and of the exhaust. Make sure one of the engine bay angles is from the passenger side looking at the turbo and downpipe.
    Find a low-mileage one-owner unmodified '04/'05 and you're golden.

    Understeer is when you hit the wall with the front of the car.
    Oversteer is when you hit the wall with the rear of the car.
    Horsepower is how fast you hit the wall.
    Torque is how far you take the wall with you.

    Called dealer again it has ACT HD pressure plate with performance street disk. But still says everything else is 100% stock. I also took pics of turbo and exhaust. Kinda dirty because rain hit while I was going down a dirt road (pissed me off) but looks 100% stock.

    Post the pics.

    You're obviously still having issues if the codes come back. Economy mode is just a waste of time.
