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.

Isn't USDM Acura TSX's uses different sort of camshaft head thingy than the Honda Euro's?
