Can it measure pressure in a fast moving air stream?
Won't the Bernoulli cause the readings to be off?

absolutely.

the best method is to place the open tube end perpendicular with airflow. using it, i was able to test the outside and inside of the hood of my previous two cars to see where it would be beneficial to place louvers to decrease the engine bay pressure, where the highest pressure was at the front to determine where to place the intake for best results, as well as the rear bumper to determine if it would be beneficial to cut it or not...

it'll take an afternoon, a sheet of paper and a pencil, some tape, and a methodological plan, but it's well worth it - especially with all the aero/cooling issues that are going on...
