I also loved the idea of 93/meth but when running over 720hp I was getting distribution issues and hurting plugs. This moved me to a standalone ECU which allowed me to have it set up as a flex fuel car with tunes for E85 (900+hp) and 91/meth (700+hp) and the ECU automatically blends the two fuel tables as needed.
If you have issues safely making that much power you may want to consider a flex fuel setup.
