Switchover is my word. Probably not the most accurate of words to choose. But there is a point around 5000-5200 RPM where the ECU begins changing the cam profile drastically. I'm fairly sure the throttles also do *something* around that same time, no doubt meant to be in concert with the VVEL system.
