Fubeca, that turned out really well. I'm impressed with the finished look. Wish my handiwork was that polished.

About your test results: what speed were you driving? I didn't see that mentioned.

You likely realize the percentage difference between A & B runs increases with increasing speed.

Brett (bondo) reports a ~20% change with his cap on the highway (here and here), but with all due respect (and I mean that), he hasn't yet done a "controlled as possible" A-B-A test. Also worth noting: he drives at 70 mph, which would show a greater percentage increase than I would see, for example, because I tend to test around 90 km/h / 56 mph.
