4.8/4l60e to 4.8/4l80e tune

Anyone know how to use efi live to merge two different transmission sections? I have an 03 lq9/4l80e PCM I was going to plug into my truck to copy the factory tune off of and then merge the transmission part to my current truck for when I do an 80e swap. Anyone got any ideas?

Just curious, i was doing some searches and noticed in the past there have been some shops doing dyno tune days with a large group of people... Anyone know if any good shops are doing this anytime soon?
