    Most tuners I know of that build engines usually make sure the engine runs, then give you a base map to go through break-in with, then have you come back for the real tunes...

    Break-in Dilemma

    Well I don't believe in totally beating the piss out of a brand new car, but doing a pull up to redline isn't going to hurt it. I personally drive it casually for the 1st 300-500 miles with down shifts and pulls to pass cars and such. Then change the oil and begin to drive the car. I by know means beat on my cars. I would refrain from bouncing off the rev limiter until the car a few hundred miles on it. But between 50 miles or 1000 miles nothing will change with how the motor operates. The motor is already where it's going to be once it hits the dealer. I'm not against the 1000 mile break in period, I just know that from the moment I drive off the lot to 1000 miles nothing is going to change and make it safer to drive it hard. I would just recommend changing the oil before you chose to drive it how you're planning on driving it.

    It's not about revving the piss out of the motor, its about the cylinder pressure necessary to seat the rings and the valves. Making sure you are constantly boosting in the first 15-20 miles of the motors life is key.

    This solves the oil blowby issues that many Subaru turbo motors suffer from.

    From Subaru (and every single other car manufacturer out there, mind you):

    Damage or Malfunction Due to Abuse, Neglect, Accident or FireThese warranties do not cover any part which malfunctions, fails or is damaged due to objects striking the car, road hazards, whether on or off the road, accident, fire, neglect, abuse or any other cause beyond the control of SOA.
    You'll have to forgive people for not trusting a single thing some random guy, with no reputation to speak of, says they should do when it direclty conflicts with the manufacturers recommendations, not to mention 90% of the engine manufacturer and tuning community.

    Even Cobb suggests a mild break-in procedure: Technical Articles

    OP, do what you want, but if you want to keep your car within warranty limits, listen to what Subaru says, not this "annihilator" guy.

    Follow the instructions of the engine builder. If the motor is stock, follow the Owner Manual. If you have a built motor, the shop will have their recommendation.

    So, what constitutes abuse according to Subaru?

    And actually, I have quite a good reputation on the real Subaru form. This method is also well known on the real forum. You guys don't get out much, huh?

    Excuse me? Maybe you should head back over to that "real" forum then. We wouldn't want to damage your precious reputation.

    I'm sick of this thread.
