User blog comment:ImperiexSeed/Jay Garrick appearing and Eobard's response to his presence/@comment-28732696-20150528123052/@comment-3481504-20150528125104

You're totally right, future Barry, by that point, seems to have mastered his powers as a Flash, and it's possible that Jay or another Flash helps him towards gaining a mastery of harnessing his powers.
