I think once you see how the test is performed its easier to adapt any number of external devices to complete the test.
All forced induction vehicles NEED to be tested. It is absolutely the basic 101 of setting up any engine for boost.
Its crazy how many people overlook this simple test and suffer consequences of leaking energy without realizing it.
