There should be an indicator in the upper right hand corner.
If it says:
0-stock
1-
2-
3-extreme

Sorry I left out descriptions for 1+2 I don't know what you have loaded on the gryphon.

I think custom option would have taken you to tire size and gear ratios.

Kind of weird it went through the whole process again. I have had mine unplugged 2 times and it just goes to hex code and then the normal heads up gauge display each time.
No I don't think anything happened to the stock tune. The only thing that can happen is if you pull it out of the truck with out returning it to stock and hook it up to pegasus to do an update or down load.
