We give the option on the Street and Performance tunes to pick 87, 89, 91 and 93 octane for each. So you can choose which octane you want for the street tune, and pick a completely different octane for the Performance tune.

For the Race tune, we only offer either 91 or 93 octane. So, you can choose which you want there, as well.

It's kind of nice because you can have a tune for each octane, or some people only ever run 93. Some people need an 87, because 91 or 93 is limited in their area. It just makes it really easy to customize for your needs!

Hope this helps!

As many posters already indicated. They will ask you questions if you call or you can fill out the drop down menu's when you first buy the Tuner.

 

I just ordered my 3 tunes all at 93...
Dont have to think about which tune i may want to run when filling up.
You will get better performance and fuel economy at higher octanes, espically if your car is set up for it. I think the 10%+- better mileage makes up for the 7%+ higher fuel prices for 93

Just pay attention, i realized the gas station i 'used to' go to only had 91.
