To me
Without I/H/E and other supporting mods, there is not much point in lowering the vtec point.

The CU2 has a lower vtec point because it has 2-lobe vtec camshaft instead of 3-lobe like the CL9. Hence at the vtec point, it is a smooth transition to extend the torque curve, unlike the CL9 where it gets a tiny bump.
