I then added a second tie to once again over the unit and to the oil inlet pipe. Hasn’t moved since.

5:56 of video. Right side easy peasy. Works like charm…

This location works with the Cargraphic? I though the Cargraphic's cables are shorter but I may be completely wrong.

I also didn't love the new bracket but understand why it needed to be changed as the new cargraphic module lacks the mounting area for the old style bracket.
I'll take a picture of my zip tie approach, but I felt it was fairly secure - used 2 zip ties to secure the bracket to the cargraphic module and then a few more to secure the module to the car (loosely) just in case the bracket itself breaks. Its been a few weeks of regular driving so worth me popping off the rear plastic and checking it out.
And agree with the others - the cargraphics makes a HUGE difference on idle and low speed, eliminating the need for an aftermarket exhaust. My only issues are:

- Turbo whistles are far more pronounced, whereas the stock PSE mutes the whistling for the most part. But I can easily go back to stock by pushing a button
- Keeping it on does cause significant vibration (and low frequency vibration) at varying times like idle 4-5 minutes after start and highway speeds. I do think there could be downstream issues with interior parts and fitment being disturbed over time, but likely would need thousands of miles to wear hopefully?

What type of double sided tape did you use for this install? And does it leave any residue / permanent changes to the steering wheel column?

If I am going to spend $600 on an exhaust Valve Controller, it should have more capabilities then just 100% Open and Stock.

Interesting! Is this SST product available? I hadn't heard of it.
And would a 50% closure truly muffle the turbo whistles without changing the exhaust sound? My thought would be a 50% would also reduce the net change in exhaust note at idle.
What is very interesting is that I get a ton of turbo whistle at low RPM under moderate throttle, BUT the turbo meter in the car reads 0 psi. I would have thought the whistle volume would correspond to the differential in turbo pressure (e.g., turbo pressure going up quickly would generate the noise) but maybe I'm wrong.

Currently only for GT3 and S/T 911s, yet they have said that a version for the Base & S on on the way.......

CEL Update 3:
I hate to be that guy, but what would you suggest I do for next steps @SupremePower?
- Upon starting the car after the most recent P04A1 code "pending" state, the CEL was immediately illuminated and reached "Stored" state (without another drive cycle)
- Removed the Cargraphic from the car, and cleared the P04A1 "Pending" and "Stored" codes one more time
- During removal, confirmed things were definitely installed correctly and all tabs locked in
- Brief visual inspection of the Cargraphic wires and harnesses look normal as well
- Took it for 3 drive cycles
- No pending P04A1 code anymore
- Everything seems fine
