Has anyone validated a throttle body spacer using a dyno pull or even a G-tech? I've looked at some of the ads for them, and they make some pretty wild claims- more HP, more TQ, more MPG. Some reviews from people who installed them say they "feel more in the mid-range", but I've wondered if anyone has proven that they work.
It doesn't seem like a 1" metal piece with some ridges in it can affect the airflow that much- sort of like the Tornado
