What functions will I lose
Looking to replacing my existing 5.2 and NV3500 with a 5.9/408 stroker with Fitech EFI and NV4500.
If I dump the existing factory ECM what features will I lose on the truck?
Cruise control? Rear ABS?
Thanks for your input.

The PCM (as its called) controls about everything. But you will lose all gauges, abs, motor or tranny won't work, fuel pump, cruise, ac, and a whole bunch more
