Read current tune and save it
Install new ecm, have it updated.
Then read that tune off and do a comparison.
Change whatever you need to change with the comparison
Stop making threads that you've already asked questions on.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
Exactly what RDF1 said.
Theres a compare feature at the top of the editor. Open the new PCM file, then click the compare button and load the original tune. Anything different will be a different color and you can copy all the values over so itll match in the areas you need.
