Need to Modify 91 racer tune

Hello, I have a 91 custom race tune for the predator tuner U7145 on a 07 gt with c&l racer kit on it. Anyways, i moved to a tiny tiny little town out in the middle of nowhere with a gas station that only sales 87 and 89 octane. So I'm looking to see where I can have my tune modified to run the 87 or 89 octane?
Thanks for your help

Lower the global spark setting by 5Â°.

Thanks

Plug in the tuner and then modify tune?
Thanks

One last question. So when I do the modification, and then decide to go back to 91 or 93. Will the new modified tune be saved on the predator and I will have to add back to the global spark setting? Sorry new to this, just want to make sure I don't f anything up.

if you change tunes it will ask you if you want to reset the parameters.
