Custom tune question

[Rustler]

I could use a little clarification on how I should check to see if a custom tune is ready.

Do I need to have the Gryphon plugged in to the computer then click updates then targeted functions.?

Can I click updates then current update status with out the G unit plugged in.?

Will I get a PM or E-mail, will an alarm go off in pegasus, will my laptop jump up and slap me upside da head?

One last thing, the custom tune is spoda replace level 1. When I do get the custom tune will that wipe out the changes I've made to level 2 tow? Or do I simply select level 2 then use reload previous settings.

Thanks...r
