Ideally, you want it so that the torque of the low cam is equal to the torque of the high cam when vtec engages. It will create more gradual power throughout the early vtec engagement instead of a surge of power and then limping out afterwards.
If you look at a dyno graph of improperly set vtec, you will see what I mean.
However, most tuners will set it a bit high because there is nothing like breaking the tires loose when vtec engages, so the customer is happy and they won't even be able to tell the difference, power-wise.
