[s-cars] YeeHaaa!

Ok, I just went out and tried this latest test. I disconnected the hose at the wastegate itself. Boost dropped from the usual 22psi in 2nd-5th to a constant 20psi with this hose disconnected. Would this lead us to believe that there is a vacuum on the bottom of the wastegate that is responsible for the 2psi lost boost? Looks to be the case.

  Thanks for the effort Chad... but that's not quite the test we're looking for.  We need an "independent" tester to disconnect the line from the WGFV to the WG (19mm socket on the line where the hose attaches to the WG), and then see what max boost is.  We also need to be sure the WG is equipped with a stock spring, not screwed down.

  By simply unplugging the WGFV, you've put it in a complete limp mode, passing boost to the bottom of the WG... resulting in minimal boost.

  Thanks,
