You mention strakes on your diffuser didn't work.
They didn't produce any additional downforce.
But i added strakes to mine in the hope that it would staighten out airflow.
That, and I think they look cool ( which means even if ineffective, I plan to still use them unless they actually create drag.
Would strakes help guide air that is going turbulent ? ( It's related the questions I asked before about using fences on cars. )

Some messengers have reported that the outboard strakes help isolate the diffuser from rear wheelhouse turbulence effects. Then go on to mention additional buffering from crosswind and gust effects. A safety precaution on the race course, or rain-slick Autobahn.
