The power thats being run isnt relevant to the optimum phase sensor gap (although RPM effects it slightly i should imagine) and the phase sensor gap has nothing at all to do with wether the spark gets blown out or not.
Are you sure you arent confusing it with plug gap? If so .013" sounds a little low to me personally.
