Unfortunately, it won't change anything. The score coming from Google PageSpeed is just one indicator among many. The report certainly helps us, but its interpretation is what really matters in order to assess the weight of each item in the report... and its relevance! Google usually penalizes your site for things that are out of your control. It is therefore important to consider it. That said, other things that may seem innocuous can have a huge impact. Only a performance analysis done by an expert, where all the available data is considered, can give you the right information about the real problems. Thus, you will know exactly what can and should be fixed on your site.
