You only get so long (30 minutes IIRC) for the DEF to warm up before you will start the derate strategy. It is progressive and mandated by the EPA, all the way to the only thing the tractor will do is idle. There are ways to get around a DEF system, and I'm sure there will be plenty of money made by people smart enough to figure it out or brave enough to risk their job on it.
