Thanks, Bill! Glad to know that the 6.0 Gryphon programs much quicker. I also noticed it holds 4 tunes instead of 3. I am definitely looking at either an '05 or '06 for reliability concerns if I decide to go the 6.0 route. Otherwise, if I decide to get a 7.3, I'll get the chip.
Followup question... is the 4.5L Navistar V-6 diesel tunable? Have you ever played with that motor? As I understand it, it's a V-6 based on the 6.0 design. Stock power is 200HP/440TQ. Curious what your thoughts are on that.
The reason I'm asking is another alternative for me to the F550 is a Ford LCF or International CF (cab-overs with the 4.5L motor) - they are plentiful and easier on fuel and are rated for more "payload per GVW" than the F550. I have some feelers out about how to "veg" them. Link:

What about tuning the 4.5L Powerstroke V-6?
