Tuned, timing advance, and octane

Anyone else logging and monitoring timing / running high octane fuel? I’m probably a bit of a logging nut because of my previous vehicle, a twin turbo that WMI / E35 fuel. I’m wondering if I’m the only one running e25 (95 - 96 octane) consistently?

I’ve been running e25 (4 gallons of e85 and the rest 93, on a near empty tank) for about 5 months now with great results with timing advance. She is definitely happier vs 93 octane. The interesting thing is I have not seen a drop in economy. I even recently averaged 26.5 mpg over 32 miles, which is pretty darn good considering I’m on 32’s / 1.5” lift. Of course, I had to keep her under 60 mph. Any other logging geeks out there like me? I’m OTT tuned. 53 degrees advance is most I have seen, of course at partial throttle. I generally max out at 30 under WOT.

We spoke, great company and guys. I’m more interested in other end user experiences and their timing logs. Honestly, I don’t really have a question about the tune it’s more about user experience and fuel.
