I've noticed the "extra" push in the pedal a while back as well. If you look on the floorboard behind the gas pedal there is a spring loaded stopper there. Not sure why it is there, or exactly what its purpose is. I just assumed it was so I don't push the pedal through the firewall.
Baseline Dyno
Well, the poweraxel guys were in Toronto this weekend working on tunes for the Genesis Coupe club and they encouraged me to put the F on the dyno for entertainment. 
Since the shop owner was a good a guy, I'll probably have the headers installed here and dyno'd again after install. One thing we noticed was the F was pulling timing on consecutive runs, losing about 10HP off the top end. The dyno results below show a good run without the ECU interfering.
Dyno Results
Has anyone noticed the pedal feels like it has a second switch after 90% of its travel? It takes a bit more force to depress.
