I would use "It causes a Large boost to Fire attack, and a Great boost to Fire attack when evolved." (added the comma - I'm a punctuation snob :-)

Otherwise, it's perfectly acceptable to me. You might also try bolding the "Large Boost" and "Great Boost" bits to point out there's a difference, but that's completely up to you.
