The XF 35t with its 340 hp can not be called just under-motorized. However, if you want to get more out of your vehicle, you will not have any obstacles in the way thanks to the Arden power increase. By reprogramming the original engine control unit, the power increases up to approx. 380 hp and the torque up to approx. 510 Nm, depending on the stock performance of your engine.
