On the good news side, you can sell those useless devices 2 me at 1/2 price 
That truly sux, this should be very much a DIY procedure. I still think it is an interference issue, but maybe not.
Not sure about selling these things. LOL. It was actually pretty sweet just walking up to the tire, hitting the "read" button and getting a digital pressure readout within 0.25 PSI. Lazy, but sweet.
It very well could be some sort of interference, but if that's the case, I would expect the source to be on-board the vehicle. I've tried doing the learning in multiple locations, including out in the corn fields, and I'm not aware of any on-board auxiliary devices or wiring that could possibly be causing this. Hopefully the dealer can figure it out for a reasonable cost.
I read somewhere that the BCM can store up to 8 sensors (2 sets of wheels), though I couldn't find any mention of this in the service manual. If that's true, I wonder what would happen if the previous owner had a second set of wheels, or had new sensors installed when the tires were replaced.
If the additional "slots" in the BCM were taken up, would programming new sensors boot the oldest stored codes in the BCM, or would a manual clearing of the BCM be required to free up the memory?
At any rate, I wrote down all the sensor codes for both my new PI wheels and the OE 20" and will take them with me to the dealer along with my scan tool, just in case.
Now to go reload the OE tune, just in case they do something dumb like reflash the PCM.
Hopefully I will be able to post a root cause tomorrow after my dealer visit.
