Hi all,

I am trying to do some work using PCM hammer and tuner pro rt using a bench harness and OBDX ProVT on a windows 10 hp laptop, The two units i'm working on currently are a 2000 silverado 1500 5.3 4l60e, and a 2000 silverado 2500 6.0 4l80e. I cant find a XDF for the 6.0 truck it uses OS 12205612, so i have been told to segment swap. I have no idea what that means so I came here to learn. I have had past success tuning using Flashhack and tuner pro rt on my 1994 Camaro LT1 and a 1995 Impala SS.
