Just had the Polestar upgrade performed on a 2013 C-30 R-Design. What a performance difference! Polestar will place software into your Volvo (all models) at your dealer. The accceleration is unbelievable. The beauty of this upgrade is that it does not compromise your warrenty such as an aftermarket chip will do. On the C-30, the h.p. rises by 27 and torque by a huge 36 ft lbs.
