I’m looking at purchasing a 2016 TRD off-road that has an OV 93 Octane tune—I know very little about engines.

From what I’m reading, tuning to that levels requires you run that level of gas. In other words, I can’t run an 87 octane in a 93 tune.

1) is the statement above true?
2) can I easily untune the truck?

I don’t want to have to pay for premium gas. I just sold my nimmer and am done with high octane gas.

Thanks much!
