While testing a vehicle, amateur automotive tuners without access to a dyno (or automotive dynamometer) may employ the use of a Bridge Dyno. i.e. Finding a hill or overpass that, when driven, applies a steadily increasing and decreasing load level on the engine. Bridge Dynos on roads with a median make excellent testing grounds as the turn-arounds can be used to repeat test runs in succession under consistent conditions.
