DemonSVT, those are some very good points.

My car feels the fastest about 100-150 miles after resetting the ECU. Also, notice that the A/F ratio is changing on its own at WOT, indicating that ECU is changing WOT fuel maps on its own! Also note that the most power was seen in Run #3, in which the A/F ratio was 14:1 all the way to the fuel cut!

It also seems that the non-SVT Duratec has much less of a dip at 3400rpm. Maybe this is because of the milder cams.
