Their dyno reads a little low. My friend's Evo back when it was a 2.3 and on the 6262 on 14lbs baseline pull made 343whp I believe it was, and then they put it in shootout mode which they said reads like a dynojet and it made 400whp (give or take a few, it was a few years ago so I cant remember exactly lol). Thats just my experience with that dyno. Good guys there though.
