Since it's factory tuned for 87, can I run 94 in my 2017 GT or do I need a tune of some sort? Also, if I do go to 94, what are the benefits?

Thanks!

Nope 94 will run just fine. I miss when Sunoco had 93 in my area.

No real benefit. I believe the advertised HP numbers are with 91+, so really it will be just that you're finally getting the most HP your car can make in stock form. You MAY also get better MPG since youre getting a better burn.

Yes you can run it, and you might gain a hp or two over running 93 as the PCM will compensate slightly for the higher octane.

And technically the car is tuned for 91, but can run on 87.
