You can't observe something without changing it (metaphorical stretch of Heisenberg's Uncertainty Principle).

I would put some yarn tufts around the edges of the bumper holes and see if they wave into the holes or out of them at speed (or maybe in and out, in and out). Some sort of attached GoPro would be ideal to document it.

Bottom line, if you really like the bumper holes... keep them! It's your car. You're welcome to enjoy it. You will be getting better mileage with the UltraGauge and offsetting any aerodynamic problems from the bumper holes (if there are any measurable).
Sounds like a good idea I have a Contour and a GoPro. Seems like I just need to find my wifes stash of yarn now. I know the nut behind the wheel is the biggest nut to crack when doing all of this, but other additions have to help too. I'm just going to keep testing, and taking ideas you all through at me and run with it.

So Yarn test will be next.
