When i started this journey last summer, ECM reported battery voltage was ~12.1-12.5V. Today, it ranges 13.8-14.2V. Am planning on replacing battery cables & adding an engine to frame ground strap this weekend pulling another log, and going from there. Am thinking a good next step is having a formal vacuum test run to ensure i have no leaks in intake or exhaust, then proceed to looking at the .bin for mismatches, like the EGR's enabled, but doesn't exist, wrong injectors defined, etc.
