18N04 FSA
Hello. Just bought a shiny new 2019 f350 with the 6.7 powerstroke. My ford app says there is a field service notice. The notice is 18N04, basically a re program of my pcm. The dealership never specified what was wrong with the current tune. My question is has anyone dealt with anything like this before. If yes what was the problem. My concern is they will re program the PCM and my trick run worse or with less power due to needing to meet some over the top emission standard from California. Any thoughts?
