from the 3 metal pipes that are attached to cam cover, 1) attaches to EFI pipe, 2) to breather thingy, also on EFI pipe I know No.3 attaches to a metal pipe that comes out near the top of the inlet side of the turbo, but where does that connect to after, I have no power steering or air con. Do I need hi/lo boost? have adjustable actuator, and boost control Thanks
