The first run was done at probably too cool an engine temperature. This may have resulted in an even more rich mixture at the top end (see A/F blue line). The second run resuled in a more lean mixture up top, but still rich as it's below 12.

The high horsepower of the day that I saw was from a Nissan 240 which output 364HP and 298ft-lb (click for image). Check out the video below - it contains a couple EVOs and the 240.
