how to clear predator of custom tunes?

[tootsie]

I can not tell what tunes are on the predator either canned or custom.
Can someone help me here? There is an option to erase custom tune is that all I have to do. Is there a way to reset it at all so I can hopefully start over.
Also can someone tell me how to modify for 3:73 rear gears. I go to enable it for the change.....then it says the change will take effect the next time you install a tune, but when reinstalling tune there are no option to chose for 3:73..it just goes to install it with modified perimeters and nothing changes. I'm sure its something simple I'm missing Any Clues? Thanks

If you restore the original backup (stock tune) to the vehicle any custom tunes will be erased at that point. Also when you are making the gear ratio change. After you make the change escape back to where it says install tune. At this point the tune you picked with the adjustments you just made will be installed on the vehicle.
