Sound symposer removal

Or maybe my ear is tuned to listen for it, and I do have crazy hearing!

Meth injection boost reference
Exactly my thoughts too....I'm wondering if this might be a possible place to tap in a pressure port for a boost gauge. I've been reading about the ford focus guys doing this and the shape of the tube flange even looks similar, but I won't know until I have mine off. It's a pain to get to...
please tell me you have found an answer to that. I have a 2015 F type R and installing a snowperformance stage 2E meth injection system on it. im planning to tap the boost reference sensor of the system in the symposer. Not sure if that will work. U’ve had any luck?

but the symposer on the f type is behind the engine and not by the intake in front of it and velocityap told me that there is boosted air there (they called it symphonizer). I am just not sure how accurate the boost reading will be. And yes im aware that obd 2 has boost values, but snowperformance boost reference uses a pnuematic hose that u connect to any charged air source.

Okay, but that hose MUST be attached to a source with direct connection to the intake manifold. The compressed air goes directly FROM the supercharger into the Intake. That is the ONLY way it would work. If a supercharger caused any boost into the intake tubes, zero air of any sort would enter the engine.

Using my limited knowledge, the symposer is attached to and gets it's input from the low pressure/vacuum side of the blower. If I'm wrong, then I'm wrong. I wouldn't see why it'd be there on the HIGH pressure side because the "SUCK" sound wouldn't be there because No Suck to make sound. It'd be pressure.
On old Chevy's, people would flop their carb's air cleaner lids upside-down so all the air would go into the filter from the entire circumference instead of just the snorkel. That gave the Suck sound. Blowers don't make suck on the pressure side.

I’m actually having the symposer tube replaced on my 2010 tomorrow. The cracked tube threw P0171 & P0174 codes (banks 1 & 2 too lean).

Glad this old thread was revived. In my quest to make my 2010 XK (N/A) even quieter, this came at a good time. I just removed the "sound-tube" hose from the air intake "Tee" and plugged the plastic spigot where the hose attaches, and put the hose back on. I didn't want to remove the tube, as a future owner might want to re-activate the option.
A lot simpler system on the N/A/ engines...
When my head cold goes away I'm anxious to see how much noise reduction I get...
