The question is what gets more power? If you go 12+ and have to back the timing out will you have the same power as if you left it stock with more timing? At least have two maps, one with e85, race fuel, or if that torco works and then regular fuel.

without racing fuel/e85, I dont think I would feel comfortable going over 11.5 or 11.7 to 1. Generally a street engine that goes higher than 12:1 is using direct injection and or cylinder pressure monitoring.
