I am not familiar with HPT. EFI Live can either do a calibration flash, or an entire flash. I'm curious to know if it still has the same issue when an entire flash is performed.

Have you tried a replacement PCM?

They're cheap enough, about $100 with a factory flash.

Edit:

Do you have an aftermarket radio or anything that interfaces with the factory controls? Unplug it and try.

I did try a spare pcm I have with the same results, as far as an aftermarket radio goes, yes I have one. But it does not interface with any factory controls
