That's a EFI Live upgraded OS number I think, you'll never find a 4L80e segment swap from a stock file on here. Seems unlikely that someone will have one here but ya never know.
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.
If a swap harness is used does the segment swap still need to be performed?
It depends on the swap harness. We have a swap harness that works without a segment swap.
