It is my understanding that the standard 250 tune turns off the EGR valve but does cycle the valve (at idle) to keep it from eventually "sticking" closed, which could be a problem if you load the stock tune in the event that you have to take the truck in for warranty work or for emissions testing.

I assumed that the 250 EGR "off" either does not offer the cycling of the EGR valve or is for trucks that the entire EGR system has been removed or has had EGR-block plates installed.

The only difference is that the EGR delete tunes allows for the disabling of the EGR (plates, full delete) with no codes. The 250 tune doesn't use the EGR while you are driving, so it doesn't matter either way.
