This only shows four users and their numbers:
Front air dam - EcoModder
Big Dave, kir_kenix, moorecomp, and wagonman76. Big Dave did not list his cost, but the other three averaged $4. Big Dave used conveyor belt on a truck, so that was a bigger project.
They saw 1-7% improvement, averaging 3.775%, for perhaps thirty minutes of work (Big Dave may have spent longer).
I have a really big air dam, so big that it covers part of my grill! I have not tested it, but wouldn't I need an MPGuino, unless I just do coast-down testing?
I need to figure out the 'guino!
Edit!

The belting material set me back about $75. Expensive and hard to work but nearly indestructible. Took about three hours including drilling holes in my bumper.
