It’s useless, just allows engine noise under load into the cabin for a “sporty” experience. It’s called a symposer, just remember to cap the hose that connects to the manifold to prevent any unmetered air from entering the engine. I completely removed mine about a year ago. No issues at all

Wow, thanks for the info, that makes the area behind the supercharger much tidier I am sure ! I just wasted my time fixing the flexible pipe :-)
@Oxidizer2k I actually did it when I removed my blower for the rear crossover pipe. Here goes a pic of when I had the manifold cover off. Looks like it can be done without the blower completely off. Just the removal of the strut bar, wipers, and plastic bits and you should be able to get it done.

So I assume you leave so this on (I am working on a Range Rover but probably the same)
Leave this port open?
And blank this port off ?

Not the easiest job, but it can be done. The whole system can be tossed away, just remember to cap off the manifold port and the cabin access tube. Everything can be tossed away. No fault codes, no issues

@kansanbrit What did you do with the port on the "Tuning Valve" that you asked about above in this thread? Please see pic below for reference. In another post above, where you say, "Done," I see that you apparently left an electrical connector hanging, but it looks different than the one on my XFR which goes to the tuning valve, so wasn't sure what you decided to do. Did you just leave that port uncapped or what?
Further, per the thread I started (with associated pix for reference) at Boost Reference: Brake Booster Vacuum Line @ Symposer???, the manual says, "The tuning valve controls the application of vacuum pressure to the pneumatic valve (in the Symposer). The tuning valve is a normally-closed solenoid-operated valve installed in the vacuum line between a T-connection in the brake vacuum system and the pneumatic valve." So, I'm wondering if I can somehow either use that port as a boost reference for a mechanical boost gauge or cut the vacuum line before it gets to the tuning valve, and use that cut end as a boost reference. Because the manual says that "the tuning valve is a normally-closed solenoid-operated valve" (assuming that's what the electrical connection is for???), I'm guessing that open port you asked about might not be of much use for boost at all times, if it's even a useable reference at all (which is why maybe I cut the vacuum line before it gets there?). This crap is confusing.
Thoughts?

I actually filled the unused port with silicone rubber but probably didn't need to. No codes. You won't be able to get a boost pressure reading via the vacuum line as it is used for the brake servo. You would need to tap in to the blanking plate I showed in my photo.
