I just sent them an e-mail asking about that, waiting for a little while before I call. I hope my truck turns out to be set up with a safe tune becouse it is fun to drive the way it is!

If you have a tune installed, it's written over the stock program on the EEPROM and is not a visible feature.

You must've missed it. The key here was "2005". Programmer only...
Also, any Ford Power Stroke since 1994½ as been fully OBDII compliant as per EPA Regulations. Any OBDII scan tool should be able to read the PCM Information and monitor standard PIDs.
The problem here is that no scan tool is going to tell you if the PCM is modified. The only way to do that is actually read the contents of the PCM and compare it against a known valid stock calibration. The only exception is in the off chance that the PCM sets a P0605 (ROM Error) DTC which is a dead giveaway of a modified calibration.
If you want to make 100% sure your PCM is stock, have the Ford dealer update it.

I am under the understanding that the EEPROM programming is similar to OBD2 but because of the weight of the superduties is not expressly covered under OBD2 legislation. Did this change in 05?

All vehicles supporting OBDII CAN communications are bound by specifc SAE communications protocols. This means that ANY OBDII compliant vehicle's PCM must communicate with any OBDII scan tool.
ODBII J1850 protocol (the earlier specification) was not as defined and could vary slightly from manufacturer to manufacturer. However, as far as Ford is concerned, ALL 1996 and later (1994½ and later F-Series PSDs) were able to communicate through the same protocols. The switch to CAN in 2003/2004 has made things simpler for the diagnostic tools industry since it is a much more documented and better structured communications specification.
One other thing to remember... Since an F250 is still under the control of "Light-Duty" vehicles, it must adhere to the same OBDII specifications as cars and gas trucks.
Hope this helps.

Thank's for all the help guys, now I'm lost...sorry...haha.. I am new to all this and don't understand all the big words you have used. I have been driving it for a few days now and love the power and don't really want to change anything plus it says that I'm getting 17.2 mpg average. with a fuel mpg that seems to be pretty good and horsepower thats unbelievable, I am very happy! I guess I just wanted to know what it has loaded on it just in case its something that would tear up the clutch or transmission.
