Hummingbird claims a wrong Pagespeed of 93/100

We optimized our wordpress site with Hummingbird to 93/100! Great job so far, but tells something different with 43/100. I think it's because of lighthouse analytics. How can I improve this with Hummingbird, because our client ckecks Google Pagespeed and not at the score from Hummingbird in the backend.
