was the tune you loaded just a generic 93 octane tune or something set up specifically for your car? if it was just the 93 octane tune you'll be fine.

you can just install them and revert to either the premium gas tune or stock tune if you have a custom oneand be fine.

yeah if it was just the generic premium tune then no worries unless you start using 89 octane.
