I got it, I had to pull the TPS off and undo the clip with a screwdriver, then wiggle is out as hard as I could with a pair of pliers. It had some water and dirt around it and it was like it was super glued.
I guess as long as you got it back on EXACTLY where it came off you should be fine. I don't know what you mean about calibrating it in your power commander. I have the pcIII and didn't have to do anything like that.
