No problems in the logs except I can't add as much additional timing as I thought I could over my 50/50 map. It may be just slightly faster but it appears that you get 95% of the gain from a 50/50 mix. I already sort of knew that, but I'm still a bit surprised that there's so little additional gain.

But my fuel trims and lambda look fine and I didn't throw any codes so far. In theory there should be a bit of gain from running it straight just from the extra cooling of the exhaust making it easier to get the exhaust through the turbine housings. And it's nice to only have to pull up to one pump and swipe the card once.
