Performance Tunes - 87 vs 91/93 Octane

[MiWiAu]

Hi Torrie,

At a high level, can you provide a summary of the types of adjustments you make and the benefits of the 87 octane performance tunes? What sort of gains would you expect (roughly) compared to the OE 3.5L EcoBoost?

Also, same question for the 91/93 tune: roughly what sort of gains would you expect compared to OE, and what additional adjustments can you make with the 91/93 tune above and beyond what you do with the 87 tune?

Thanks!

I adjust both engine and trans function. The higher the octane the more power that can be made.
I would estimate
93 40/60
91 35/55
87 20/40

91-93 files would net higher boost and advance with a slightly altered AF curve above something geared for 87.
