It is really not due to the cam profile, but the uneven firing (1,3,4,2) of 4 cycle 4 cylinder engines. Due to that, the power strokes do not over lap, each piston must complete it's own power stroke and come to a complete stop before the next piston can start it's power stroke. This creates pulsations in the power delivery, most obvious at low RPM's. I think this along with a more open exhaust (less back pressure), is creating the "cam lope" you are describing.
