Dan, my system is like yours-cable driven from the accelerator pedal to the pot under the hood. I just tested it and my throttle actuator rod goes all the way to the stop in a delayed, notchy fashion. In response to a "floored" pot it initially responds immediately to open approx. 50% and then continues to open in notches to full throttle over a period of 2 to 3 seconds. It will only do this 1 or 2 more times before the key must be recycled to get the same response. Hope this helps.
