Hello Fellow Enthusiasts,

I have an engineer friend who is curious about the Polestar dealer-installed upgrade. How much added boost does it produce from the stock boost figure, and what is the stock figure? I have visited Polestar's website and all it shows is the roughly 8-9% increase in HP and Torque, but nothing as to the boost pressure. Does anyone know these figures or can they direct me to someone or a website that can provide them?

Thanks!

Clyde
