Today I took the intake line to the turbo off and was able to watch the fan inside turn. I tried to move the wastegate actuator linkage but it was froze, this is a non-ac truck.

I also bypassed the gizmo on the drivers side fender. When doing so I noticed a t in the vacuum line. The line goes from the ip to the gizmo and from the gizmo to a T. and from the t it goes to a small vacuum pump underneath the coolant reservoir where the vacuum comes from and then there is a loose line on the T. This line is of larger size than the two vacuum hoses. With the truck on I can feel a vacuum coming from the open line. Should this be hooked up somewhere or does it need to be open so air can come in for the vacuum?

Truck is warming up right now, gonna go try her out and see if I can notice a difference.
