Obx itb vacuum line help

[dallasb84]

First timer here when it comes to doing an itb setup. So far so good but this vacuum line stuff is confusing me.

Basically I need to get this thing together correctly an on a trailer straight to the tuner with no problems.

I have 4 ports that seem to be exactly just before the butterfly valve. What are these 4 ports for?

Secondly. Is it best to use a vacuum canister with a map on it? Or will my golden eagle suffice as a vacuum manifold?

Thirdly. Screw the ports on the itb and tap my own after the butterfly to a vacuum canister mentioned above.

I am boosting in this application so I need tps, map, and iat sensors.

Thank you so much for the help guys.

If I am wrong please shoot me straight like the gheys ain't.

Peace.

Throwing away the obx pile is not an option. Neither is burning this bucket to the ground. I have points standings for the year I need to keep up on.

Also.... With the itbs what is the best initial gap to set the butterfly valves to? Like placing a feeler gauge in there and locking down the linkage to index properly.
