The VSS is a feedback for the cruise control (vehicle speed), more than a limit switch, it is required for the cruise control to operate. The stock cruise control can still control vehicle speed with a different pulse/mile count, as you will be setting the desired speed to a different setpoint as well - the setpoint and feedback are shifted equally. (If your desired pulse frequency was 100 Hz before and has gone to 145 Hz now, the cruise control can still regulate to the new speed.) The cruise control does have an effective maximum, but it is well in excess of the speed limit. The cruise control also has a minimum engagement speed, but I think you will still be able to use it on the highway.
