I appreciate the advice from you guys.

Can you expand on what you mean by saturation?

Are you saying the profile is as good as its going to get and I won't see much improvement modifying the boat tail anymore? Therefore, I need to focus on the rest of the car.

Also, I finished the bottom section of the boat tail I just hadn't when I took that picture.



Edit: Assuming I am correct in what you mean by saturation I think I have some useful information. On a particular road in town that was recently repaved and has a 55 mph speed limit the tail makes absolutely no noise. If there was a lot of turbulence the unsupported sections would flap around right? The road is decently protected from crosswinds on both sides by trees and buildings.
