406 performance software (NOT VOLVO)

[StitchVR]

Hi everyone.
I recently bought a 2019 Volvo V60 T8 Twin Engine (SPA platform) and have started exploring OrBit.
I noticed the following configuration items:

• ID 049 – Performance Mode
  
• ID 374 – Polestar Level
  
• ID 406 – Performance Software (NOT VOLVO)
  

Has anyone tested these on a V60 T8?
I'm mainly wondering:

• What does ID 406 actually do?
  
• What is it intended for if it says "NOT VOLVO"?
  
• Does it unlock any additional drive modes or performance-related features?
  
• Does it change throttle response, transmission behavior or vehicle identification?
  
• Does it require additional software to have any effect?
  
• Does ID 049 enable anything useful on a T8?
  

I'm not looking for guesses. Has anyone actually enabled ID 406 on a SPA V60, V90, S60, S90, XC60 or XC90 and observed what changed?
I'd appreciate hearing from anyone who has tested these settings and compared before/after behavior.

ID 406 must be Polestar software.
