Adjusting Tire Size in my tune

I searched and couldn't find a definitive answer so hopefully someone here has it.

I have Idaho Rob tunes with an autocal. I got it unlocked when they shut down shop.

Do I have to pay another tuner to adjust my tire size or can I do it myself since it's unlocked?

Thanks for the help.
