I don't know if that lip is enough to make a big enough difference in drag to make a 200 rpm difference at speed, but theoretically, it is possible.

Like I said, I did not take note of the rpm prior to installation, I forget that I have a tack most of the time (automatic). No going back now I like the chin spoiler too much. I'm not sure I understand how going faster and using more power/energy does not mean the engine will be forced to turn faster when in top gear. I'm sure that if I tried to go 100 mph that the engine would be working harder and the tack would go up, way up.
I spent all day yesterday doing city driving (many short trips), so this might throw off my first tank full. Even if I get what I usually do, it will be an improvement.
I had to go to a job site yesterday, traveled on terrible road in the woods. I'm just glad I didn't go any lower with the spoiler.
