I loaded the canned 93 octane cai tune.....runs well, but i am interested in trying the 91 octane cai tune based on the quality of gas...I plan on still using 93 octane fuel, but want to see if the car runs better....

when switching to this tune, do i have to reflash the original backup first, or can I just switch to the 91 tune?

nope... don't have to go back to original first... you can just install it over the other tune.
