Current is max at low RPM and drops of as the car gets moving. CL limiting should have no effect on top speed unless it is turned WAY down. Not sure if I can find an old electric motor dyno sheet to show the effect but you should not need this featuer due to how the motor uses power.

This kind of shows it but you have to look at the graph.



At high torque you get high amp draw and this happens at low RPM. As you increase RPM you loose torque and amp draw goes down. So basically to keep get the car moving you get high amp draw to move it. To keep it going requires less torque and power and amp draw is reduced.
