87 Octane vs. 93 Octane Tune Question

[Weasel1]

For a ‘17 GTPP, how much difference in gains and feel is there between an 87 octane tune and a 93 octane tune? What are the key differences between the two?

I see you mastered 3rd grade math.......:first:

In a nut shell, timing and cam advance cannot be maximized with 87 octane. Increased throttle response is about it.

The stock tune can already adapt to the 93 octane and net more power. I don’t think you gain anything with a 87 octane tune.

The key difference is just like any other tune that runs on higher octane. The higher octane, the more timing can be ran. E85 if you want to maximize your gains. 93 is perfect for me because that's all I've ran in the car since I've owned it.
