Correct. You run your boost source from the turbo to the side port. Then if your using a boost contoller you T into that hose and run it into the boost controller "in" and the boost controller "out" you run it to the top port.
That way the wastegate will open on spring pressure and the boost controller will force it closed until your desired target is reached.

It's a good thing you hit a cut cause the way you have it hooked up you will hit full boost that the turbo will give.

Plug the other 2 AIR ports then just leave the other ports that are unlabeled open.

I want it to just run the spring pressure.
i have the 444cc injectors if that would make a difference on this setup.

you all tell me what I need to answer and I will.
thanks for the help.

I think it might be helpful to see what the afrs are doing, could you get the wideband hooked up?
What ecu/ tune are you using?

I could go get my exhaust welded up right tomorrow, but until then no.
I had to cut my exhaust so now it needs flipped down is all.
