Hello, I’m thinking about whether I’m getting my XC60 BJ 2014 MY 2015 a performance increase, in which acceleration I’d like to have a little bit more pull. Now I’m faced with the painful and already much discussed topic: performance increase by whom? For me Polestar, Heico or the Racechip are a question. Polestar: +34PS +20NM €1,199,- Heico: +49PS, +70NM €2,014,- Racechip Ultimate: +51PS +108NM €479,- With the Polestar, the torque increase is a little bit low, but I’d like Heico very much. Interesting of the price would be the Racechip, where the torque increase is too high without damaging the vehicle. I would have been interested if someone had already experienced the racechip.
