Second that, on a stock vtec motor, you will MORE than likely LOOSE power no matter where you set it.
Ur vtec will not engage as "agressively" (loosely used on a SOHC) if you set it to a lower RPM and it will be too late if you set it to a higher RPM.

Definately not something you should F around with on a stock engine!
