I just finished rebuilding a gen IV 6.0 to replace a gen IV 5.3. This is going in my 2012 Silverado crew cab. I can read the stock tune for the 5.3 but can't seem to find a starting point for a 6.0 stock file. Any help will be appreciated.

Might have something with the same OS to start with

This is the original tune for the 5.3. I thought about just trying to convert it. Although I wouldn't have a clue what the max ranges for the 6.0 should look like.
