When he did the modification I saw the following options: polestar optimisation, polestar engineered edition, polestar engineered car and polestar car. My brother chose "polestar optimisation", I don't know if this is the option that adds the most power to the engine. Also I am going to subscribe to Orbit and modify it as well, however I have seen people say that for the T6 engine, polestar on Orbit does not add HORSEPOWER, it only changes the shifting of the gearbox. If I want to add hp to the T6 I need to go to a dealer and swipe in the official polestar software. Is this true?
First, check your VIN number here , it will provide you the info you need. The part number and the optimization #.
If you go to the dealer, the MRSP is about 1250$ (only software), this price is same as on VIDA if you purchase yourself. In addition to software price the dealer is charging you for labor too but sometimes dealers do coupons or discounts. The cheapest I heard was around 900$ + labor.
I know, the name "Polestar optimization" sounds fancy but the feeling is very different from driver to driver. I went to my local dealer and asked for test drive before I spent 1250$. They gave a me test drive on S60 T5 polestar. (same as mine), I compared it to my dynamic setting right after I'd driven the polestar one. I must say, the difference I felt would not worth the cost. The +HP it gives you, it's at the peak rpm, yes it holds the gears just a little bit longer. Up shifting was smoother with polestar but down shifting was smoother with stock dynamic. (the shifting is what Orbit modifies; exactly what I felt with the official polestar) Second, is the gas pedal optimization (sensitivity). Polestar is more sensitive than dynamic mode. People also describe this as "responsive".
I prefer, manual shifting If I want to drive in sports mode.
One more thing, if you modify it via Orbit, you must revert back all the modifications to stock before visiting the service or connecting official VIDA.
