I will list what mod's I know before getting to the meat of the story. My buddies 09 Sti is a pro-tuned stage 2. I think he has a couple of other mod's but not sure. He dyno'ed at 318 awhp and 320+ awtq. My other friend has a 2010 Wrx wagon that is stock except for a cat-back and a few suspension mod's. My dearly departed 09 Wrx sedan was Cobb AP stage 2, lighter wheels and tires, and a few other suspension mod's. So a couple of months ago the three of us decide to go on a mid-night ride through some twisties. Very isolated area that we have driven many times. Anyway as we finished up our ride and hit the highway for the ride home, we were treated to a two lane blacktop that was empty and open. As we started up the on ramp my two buddies open them up and take off. I, being the worlds most spectacular driver miss third and I'm out before it begins, but I notice that my buddy with the 2010 is neck and neck with the Sti. As I catch up we all decide to do a few pulls against one another and see whats up. So the 10 and the Sti line up and go at about 55 mph. The 10 holds pretty well until about 90 and then the Sti just pulled away. Next I line up against the 10 and we hit it at 60. He jump hard on me and stayed there until I went into 4th. By the end of 4th I had caught him and was beginning to pull. I was completely thrown off by how hard he jumped me. We talked and both were in third as we went wot. I can only assume that the AP tune delayed my boost while his went insta-spool or something. Anyway just thought I would share. All the out comes were as expected but I still to the day can't get over how well my buddies stock 10 held against us.
