Shift firmness and timing questions

[banks]

i got a question reguarding the shift firmness, once i have adjusted it to what i want. do i scroll down to load previous settings and hit enter says loaded pervious settings. does this mean that changes that i made are loaded. or do i need to scroll up where it says done and reload my performance tune. its hard for to tell if changes have been made b/c im making little steps at a time and what to make sure im doing it the right way
