I believe the cut off for WOT is 95%. If you are consistently above that when you put your foot all the way to the floor you should be fine.

If you want to test or adjust your TPS you need to check the voltage running through the wires. I can't remember which ones, but I feel like it's the middle and front ones, not the rear. I could be wrong though. Turn the key to the on position, but do not start the car. When closed the voltage should be .48-.52 volts. As you open the throttle it should smoothly climb to ~5 volts. Those numbers should roughly correspond to your throttle percentage (.5 volts being 10% of 5 volts, 2.5 volts being 50%, etc...).
