What Jersey said is the truth dude.. there is no such thing as a Performance chip for the Subie. That link you have is to send your ECU in for a re-program. I personally have not heard of that outfit before. Doesn't mean they suck, just don't know them. The only people doing 00RS re-programs is i-speed and Yoshi. Both have decent reputations on here, you can easily search for a wack of info on them.
