Is it a problem to use two different tuners using LS1-edit?
Lets say you had some work done by tuner A (headers, throttle body, etc.) and had your PCM tuned using LS1-edit. A few years later, you decide to have a heads and cam package done by another tuner, tuner B, and have a tune done as well. Tuner A is now either out of business or no longer has a record of your edit. Would it be a problem for Tuner B to run LS1-edit in any way? Just curious.

The only way it would be a problem is if the first shop locked the PCM when it was programmed, my PCM was locked by a tuner and I needed to have someone else program the car so I wound up trailering the car to the dealership to have the PCM memory wiped clean and then have them reload the original program.

Good Quest Alex! I actually was thinking the same thing. Wonder if i can "hold something" to reload the original stock program if i needed to run to chevy dealer and back to the custom tune after.
