There are plenty of myths floating around here; I'll believe the factory literature. Besides, do you really expect a 20yo car to work exactly as it did when it left the factory? I wouldn't expect boost to still be the same unless the car is completely unmodified and every component is in brand new condition (engine, turbo and cats in particular).

Well thats the first literature Ive seen with boost on it. Ive always seen people say 5.5psi is the factory boost pressure. Now I know. You learn something new every day I guess. Not that it matters anyway, who wants to run stock boost anyway

You're running less than stock boost...

One more question/check. The Twin Scroll Solinoid is the green dot one correct? The FSM says something about a green plug So I imagined it would be the corresponding color. But for some reason I have 1 solinoid hanging loose, which is how it looks in the picture, so I thought it was the correct one until I saw a yellow dot. So final check. 2 pin green connector to green dot solinoid valve? hose from straight nipple to manifold, angle nipple to twin scroll actuator. check valve between the solinoid and manifold pointing to manifold?

Correct and correct.

But for some reason I have 1 solinoid hanging loose, which is how it looks in the picture, so I thought it was the correct one until I saw a yellow dot.
That's the EGR solenoid valve, like it says...

So final check. 2 pin green connector to green dot solinoid valve? hose from straight nipple to manifold, angle nipple to twin scroll actuator. check valve between the solinoid and manifold pointing to manifold?
