You wouldn't boost at all..BTW, to answer your question about adjusting the WGA, there's no way you can do it unless you modify it with some welding skills on a 16G.
Here you go. YouTube - Boost Leak Testing 201: Using the tool.Just to add a little bit, use some bubble solution (dishwasher soap with water) and spray anything that is pressurized. Leaks will actually be visible this way.
Well since his WGA went out, he must've been boosting like crazy which also means that his ECU was probably "trying" to compensate by injecting more fuel which would explain the bad gas mileage. Even with all that fuel being injected, he was probably still running way too lean.
