He is correct. It usually involves some disassembly of the engine so they may not always know. But you can bet, if there's a major engine failure, they will tear it down and inspect it. The cost of that will be significant if they find the vehicle had a tuner or chip.

That said, I wouldn't tune a modern vehicle in warranty. Just not worth the risk.

Here is step one on the Ford service guide when doing drivetrain repair.
To confirm the vehicle has a Ford Production calibration installed review the PCM calibration filename located in the IDS vehicle log file. The filename (Identified in IDS as PCM_FILENAME) must begin with the prefix letter "D" to be a valid FORD production level calibration.

It is true. I was part of the initial discussion to detect a tuner. We could 100% detect it and set a warning for a Ford tech that could not be removed. Once it is set it is always there. It cannot be deleted.

I hate videos. 38 seconds of BS music. Then all the way to 8:50 to find out about additives.
All we needed was a sentence that says: "The only additive really worth a flip might be anti-gel if you go from a warmer to a colder climate with a diesel".
12+ minutes of video.

He said nothing about the CP4 wearing out because of the lack of lubricity in U.S. diesel fuel. Is this because the 2020 model has an improved HPFP or he doesn't want to admit that their is a problem and lubricity is needed. Since he wasn't specific in the question, the answer was also unclear- is this for the 2020 model or all of them?
