Updating Edge CTS to Gryphon

[JBell]

Hello all new to the forums. Since it has been virtually impossible for me to get through over the phone to php I figured I would just post this here.

I have a '05 F150 FX4. I have an edge CTS and was looking into updating it to a gryphon so I can have custom tunes. My truck is stock (besides the chip, lift and oversized tires), Would I benefit from the custom tunes over the canned ones although I dont have any other engine mods?

If so how much of a performance boost can I expect from the canned tunes to the custom tunes by php?(hp and mpg)

If I did do the update would I need to send in my CTS? Or do I get all the updates and custom tunes via email?

TIA
