Waiting to see if the code comes back.

It cannot show 100% true TP, the GM voltage is approximately 4.2 volts at WOT. Therefore, WOT is shown at approximately 80-85%. Commanded TP will show 100%. I would assume that if you log both you will see the reason for the limp mode, commanded will be 100%, however, the actual will some number far less than 80%.
