Having fuel pressure is good until you don't. There are other indicators that something is wrong, and even I myself have had some good pulls then one randomly backfires because of fuel pressure dips.
I've been following his progress in comments etc. I just don't agree with recommending it at all. 5% or so difference to clean up timing, sure. But you're asking for trouble running that long term. That's why his STFT goes up to 17%. That is not safe.

Something must be wrong with your set up if you're randomly getting fuel pressure dips and backfires. I never get this. What are the other indicators that something is wrong?
STFT's up to 20% are fine, stop being dramatic. As long as the key logged values are OK I'm not worried. Running meth IMO is far riskier.
For comparison here's a log from July (cooler ambient temps) last year with the same map and E40 fuel mix. The STFT's are almost identical, as are all the other values, so I don't see what your concern is.

The car runs the same dragy and quarter mile times on E85 as it does on E40 as the map targets torque and fuel can't increase map torque values. Runs great, feels very strong.

There is sense for me. I know there isn't any measurable performance benefit from E40 to E85 with this map. I don't want to run a custom map and I'm happy with <7 sec 100 - 200 km/h and 10.9 sec quarter mile performance. I want to fill the tank with E85 for convenience and reduction in reliance on fossil fuel.
