@18Ventura, super helpful write up. I plan to purchase the FP Tune tomorrow. Thanks for the context and for sharing your experience.

Awesome write up and review! I think I’m sold on this tune other than it requiring premium fuel. Or I should requiring it at all times. At least that’s what I read on a FP tune document. Not that I can’t get 93 all the time where I live but I do like the flexibility of being able to use 87. Like if my wife decides to fill up with 87. Unlikely to happen but still. That’s why I appreciate the idea of an auto octane tune from Zfg. Decisions decisions.
20+ years at the drag strip has taught me about DA, track prep, etc. And temps are only part of the equation on which DA is calculated, which also includes barometric pressure, elevation and humidity. One must also take into account any change in fuel type (I only use Premium) and vehicle weight (full tank of fuel vs. 1/4 tank) and removing extraneous items from the vehicle (tools, equipment, etc.).
Lastly, my Dragy consistently reports incorrect DA (actual temps are often 10-20 degrees lower and reported altitude is off by several hundred feet), but luckily, Dragy submits that "data" for informational purposes only.
I use the below DA calculator and my local weather reporting agency to compute DA and am therefore able to keep my results comparative.

Because that’s what she has used her whole life and frankly what I use most of the time in my ST. So out of habit, the 87 is always picked. At least for her. Just like the 91 is clearly a habit for your wife.
but either way, I just don’t like the idea of lock in to premium. But I suppose I could get use to it.

I'm glad some of you found the review helpful. 
I neglected to say that I always run 93 octane. I'm not sure what results others fuel grades might yield.

LOL. We have 2 kids in college atm. Probably not gonna be re-locating any time soon. I’m pretty sure it’ll be available to 22+ owners in CA eventually. We’ll just have to wait a bit longer then every1 else. It’s CARB legal through 21 so it’s probably gonna be the same situation like the Whipple stage 1.
