"Original" settings
I just got a 2004 F350 with a 6.0L power stroke engine. Shortly after my brother bought the truck, his city required him to change the chip for better emissions control. He told me the truck lost a lot of its performance after the change. He installed an SCTX4 tuner. If I use the tuner to put it back to the original settings, will the settings return the OEM plant settings or the "chip" settings?

The SCT should "download" a copy of whatever is on the truck when you very first tune it. It ASSumes this is "stock"....and indeed there's no way SCT should know otherwise.
So, if you remove a tune and select "return to stock" it takes whatever it saved initially and loads that back. There's no way SCT could know or would want to assume liability for making assumptions about variations in ABD (as-built data). So, it just takes EXACTLY what was there and puts it back.

VERY weird. I didn't understand that part at all. I know in places like underground mines they'll deliberately de-tune diesel pickups, but that's a private company and extremely specific use case.

I'm going to go with he bought it tuned, had to get it reflashed to a stock tune once someone hooked an emissions computer up to it and saw it wasn't on Ford's list of emissions approved programs, and he then got an SCT to put a canned tune back in. In that case, reflashing the truck back to what that tuner would call "stock" would be to put whatever tune the tuner replaced when it pushed it's canned tune over.
Not sure what all was on it before, but depending on what was in there originally there several PCM and FICM tunes that significantly change tip-in throttle response - that can lead to an immediate "it has less power" feeling even if whatever was in it wasn't all that hot a tune to start with. When I bought my Excursion I thought it had an engine problem because I hadn't driven a factory tune in so long.
"Chip" is 7.3 language, 6.0 is usually done all software unless it was an Edge SOTF system, there were a few more module based tuners out there but not many as popular as the Edge.
