Platform recipes (3)
- The 6.4 reliability package (modes fm-64-head-cracking-tunes / fm-64-piston-ring-failure / plus cooling discipline): stock the truck against its two tuning-adjacent killers - head cracking on advanced-timing tunes and #7/#8 ring scuffing from regen fuel wash
- Emissions-side repair (modes fm-64-egr-cooler-hydrolock / fm-64-dpf-clog): the 6.4 has TWO EGR coolers (primary 9P456-C and secondary 9F464-F) - both are suspects in coolant-loss/hydrolock, and the hydrolock path feeds cylinder #8 at shutdown
- The K16 high-pressure pump event (mode fm-64-hpfp-destruction): the 6.4's signature catastrophic failure
