You will be fine. No problem running an 87 tune on 89 oct. You just can't do it the other way around.maxxguy1 wrote:new here and want to purchase one of your tuners

There is not a 87 octane tune (at least named like that) I have read here & there (do a serch on the forum) that the MPG booster tune is actually a 87 octane tune if that is the case (I think that Mikel posed that somewere) you will be fine using 87 fuel with that tune.
