Do you understand variable valve timing? Below a certain rpm it has VERY mild cam lobes/timing/fuel curves to help fuel economy and driveability. At the preset rpm it pulls a COMPLETE change for when you need the power. If you want the power, be at/above that rpm. Not a hard concept to grasp. If the LSx motors had that people would LOVE it. Do you go around racing from a 2,000rpm roll? Probably not, because it's COMPLETELY out of your powerband. Just like a 5mph roll is for an S2000.
My cam opens up at 4k.
I can feel the power difference there.
I've driven both an AP1 and AP2 s2k and haven't felt any difference minus sound.

It's not a drastic (OMG VTAK!!!) kind of pull... it's more of the fact that the torque curve (however small it may be) remains flat up till redline, and the power builds faster above 6,000rpm. It's not a big hit, but you can feel it get stronger. Just the nature of the motor.
