Looking good so far. That's some fast ecomodding.

You might want to check your kamm angle. Looks a bit steep. biggest gains come from between 10 and 15 degrees. It's real tempting to go for the steep angle but even if the flow stays attached, it creates lift and with it drag.

Keep on modding!

Added: Could just be the camera angle that makes it look steep.
