I would definitely see if you can get it checked out by a good subaru mechanic. See who the tune was done by if you can. If it was done by "Thorne", first name Bill then it has a good tune on it (I just had him fix my tune that was completely effed up by Slowmotion Motorsports (in Columbus)). I will contact him (Thorne) to see if he has any info.
I found the dyno run on youtube...
