Updates? none to be had, really. The 3-M adhesive tape these VG's come with rocks, they are still on super strong. They are still bending the airflow, but fuel economy benefit is still negligible.

This is definitely not the magic easy way to cut drag though. Focus on grill blocks, flat under-tray/underbody panels, and wheel covers, mirror deletes, etc.
