Low revs off throttle

[Django]

I'm noticing that the car pulls low revs when off throttle (at low speed mostly cause it's an auto). Has a plumb back fitted so nothing to do with that. I noticed the car has two outlets that are not connected.

EXACTLY like what happens here at 1:02, but my lines are metal.



Wondering if anyone can clarify that this would be cause of the problem cause none of my lines are hooked up. Wondering if it is which one needs to be hooked back up and to where?


Cheers

Your wastegate needs to see manifold pressure. Normally this will go through a controller (either a factory or turbosmart like in the video) if it is open, you will have a vacuum and boost leak. This will make your idle high

1st post edited to say 1:02

just to clarify, the idle isn't high. The wastegate is connected to the boost tee and correctly connected to the boost source on the turbo but the previous owner has not sorted out the connections mentioned, which I would have thought had more to do with the ECU seeing the pressure?

I can only assume that one of these connections used to run to the outlet on the pipe between the turbo and intake manifold? and the other to a canister?


ok also got a little confused I see what your saying now


any idea which one I'm hooking back up?

Or do I just unplug the thing...
