A few simple intune questions....

[Mossyoakglock]

I have a few simple questions that I hope are easy to answer.

1. What is the latest update on the i1000 for GM trucks (2008 specifically). I'm not sure what version I currently have.
2. I had to get a new computer and can't find my truck's stock file on my old one so I need to pull it off the intune. When I plug the intune up to my new computer, will it automatically start trying to update or will I be able to cancel it and pull the stock file to my new computer? Should I take the truck back to stock and then plug up the intune to make sure I don't lose my stock tune if it tries to update?
3. Where is the stock tune located on the intune?

I currently only have AFM turned off with -20% TM reduced on the trans. Wanting to retune with the 87 Octane Tune and keep AFM off.

Truck is a 2008 Silverado 5.3/4L60E w/ 117,000 miles.
