Deceleration Fuel Cutoff (DFCO) parameters for a manual transmission are different vs. an automatic transmission, which is the primary reason I start with a manual trans flash.

Perhaps TunerPro has a 5.7 LS1 Manual flash available?

Can you screen cap some of DFCO settings? I'm starting with a BIN from a manual 6.0L truck, the issue I'm having is the engine is stalling when decelerating.

The route cause I believe is that I don't have a VSS installed and won't be installing it, I've read that lots of people have tuned around this just wondering what to change?
