All, thanks for the support! I can't wrap my head around the near-instant mileage gains. I'll await the pump numbers before calling them official and really believing them.
However, at this point, it looks like a 4 mpg gain! In combo with having the grille and fog blocks in place, I'm showing 63-68 mpg commutes in rush hour traffic, which is a huge jump for me.
The car also feels a ton more stable at speed. I'm driving the a couple of fingers at 6 o-clock and a huge smile on my face.
Finally, while not a numerical improvement, I've had quite a few people come up showing interest and wanting to know more. So knowledge of hypermiling and eco-modding is spreading a bit faster in NC now!
