Just to be clear on this....

The 7.3L does not have a "limp mode".

What you experienced was a PCM reset and the dead accelerator pedal was due to the PCM not recognizing the idle validation switch signal. You didn't hurt anything but why it happened is unknown at this time. I would verify the chip mounting to the PCM but that shouldn't cause the issue you described. It may have been a fluke, a switch problem, or a calibration mix-up. I take it that the chip has worked flawlessly up until that point.
