Just a couple words of advice:

When running E85, do not go one boost (even a "hint" of it) until the car has warmed up. Because the plugs will be fouled from the rough cold start. During the warm-up (which can take several minutes), the plugs will clean up and then you will be good to go. But I can see a scenario where not enough warm up time was given and each attempt to run under boost causes more and more fouling. Making it take longer and longer for the plugs to clean up. Unfortunately, this is the downside of running run strong E85 mixes in winter. Not much you can do about it unfortunately. Although we are looking at things that could possibly make cold-start less choppy.
