Looks like the dyno operator did the same thing as Prodigy's dyno operator: lift off the throttle and stop recording after peak power, rather than running it all the way to the rev limiter

If the torque curve continues the same general downward slope as it does in the 5000 - 6000 rpm range, then it looks like it would be right around 240-250 ft-lbs and around 297-309 hp at 6500 rpm.

Also worth mentioning: that severe dip right at 2500 rpm seems to be an anomaly. The other dyno runs from today show a nice smooth line from 2250 to 2700 rpm, as if that entire valley was completely filled in... and as if the hump in the stock torque curve were chopped off level from 2250 to 2700 rpm. This makes me think that dip at 2500 is probably something that needs to be smoothed out in the tune.
