It increases both BHP & Torque by 20% in default. There are a set of 4 dipswitches (all OFF in default) that you can Increase/Decrease the power by a further 30% (that's 130% of the 20%, not an additional 30% of the 150bhp of the 1.9JTDm). I originally set mine to full wack (190BHP) and the torque was unbelievable for R3EHB1.
