Unfortunately the CL's speed limiter is programmed into the ECU so the procedure of "removing" it would not be a painless or easy one. I suppose that you could always take your CL to a reputable, local high-performance shop where they could reflash or reprogram your ECU but that may prove very expensive.
What makes you think there is any sort of governor or limiter in the car at all? The things will run to the red line in any gear they have the power to do it in, there does't seem to be anything stopping one from going faster than I can see other than lack of power.
