I will tell you the honest truth since I am not associated with this plugin.. WP Engine is really not that smart lol.
Take a look at this.

As we can see your website has a lot of JavaScript and CSS files.
I would drop Better WordPress Minify and instead use Auto-Optimize its a much smarter and a more powerful way to optimize your CSS and JS. I would enable the default settings, and check the cache every so often to make sure its stable if its not you will need to disable inline js optimization but for this website you should be fine.
I would also recommend that you setup CloudFlare and enable these settings.
CDN + Full Optimization (you will see this on the setup screen).
Rocket Loader: Automatic
Now your website will have a CDN, properly compressed CSS and JS, as well as all JS inline or not being deferred.
