planning on doing a lot of willamette valley mpg testing at various speeds tuesday as i do a gold panning trip to south oregon. will update on that.
and did another drive around tonight with the cardboard diffuser. def changes how the car feels, sounds and handles. i can '' feel'' the downforce, but i cant tell if there's an mpg gain or not. will try later this week on wed or thursday to do an a-b mpg highway test late at night with and without the diffuser
