the output test is useful only if the WGFV fails the test. i had problems with inconsistent low boost. sometimes i got normal boost, and other times i just got wastegate spring pressure (about 6 psi). the WGFV passed the output test. after i tested a number of other things, i kept coming back to the WGFV, which passed the output test every time. the output test actuates the WGFV about once every second, and i suspected that the WGFV was failing at higher duty cycles. replacing the WGFV fixed the problem.
