So as the title states, who has done one and what problems did you encounter?
I'm currently changing from the 4L80 segment swap to a 4L70 file and going to utilize a Frost Conversion harness. I've been having a hard time with getting the truck to operate well with Speartech harness, front ISS lead, and 4L80 file from a van. The problems being:
1. Jumpy speedo from ISS crosstalk.
2. False Torque Management Signals which cause an extreme reduction in ignition timing.
I'm going to update this thread with pics and info to clear up some of the muckety muck about an 80E swap.

Anyways thanks for all your help and advice on the phone. Your guys actually taught me something about HPTuners that I didn't know!
