Also, if you hadn't done so yet, remove the splitter in the scoop and replace with a mesh screen. I foil taped the screen to the ic, allowing more air to flow over the hot side, also foiled the sides of the ic and added spacers to increase the pitch on the ic.
the rain gutter drip is 3" tall...so that's a 3" decrease in distance from the bottom of the car to the ground...so perhaps some other factor is at play to explain why the ground skirts are not showing an mpg increase.

Can you take a picture of your Intercooler setup with the mesh screen? im a visual kind of guy so i want to make sure me and you are on the same page.
