Don't forget these:

?d

is the same as 100 and save a character

puts :Fizz

will print Fizz, just as well as :Fizz and saves a character, and if
you really want to save a couple chars figure out how to only have the
Fizz and Buzz literals and combine them in the multiple of 15 space.

All that having been said, my solution (not golfed) will include something like:

module Enumerable
  def map_every(n)
    m = n - 1
    result = []

    self.each_with_index do |elem,i|
      if i % n == m
        result << yield(elem,i)
      else
        result << elem
      end
    end

    result
  end
end
