I've experienced better results using an original manual transmission OS with a Manual Trans. The Deceleration Fuel Cutoff (DFCO) can be problematic when segment swapping a manual trans into an automatic OS.
When I flash a 5.3 liter for manual trans (5.3's were not mated to manual trans from the factory), I'll start with the a 4.8 Manual OS and hand pick the 5.3 Engine Parameters I will swap (Fuel / Air / Spark). Using a complete 5.3 engine segment swap into a 4.8 manual OS can adversely affect DFCO.
Knowing you have an Inline 6 vs. the 4.3 V6, it's anybody's GUESS what DFCO will actually look like. At this point in time, there are other "Things" to work on. The trans segment swap posted above is a good "best guess" or starter .bin file. Keep the forward progress going, tweak DFCO some other day.
