According to BMW, this X4 F26 produces 190hp, engine power. On dyno it was measured 192hp on stock software. With an #Etuners Stage1 ECU remap, power increased to 222hp. Because of the automatic gearbox, it is not possible to see the true maximum torque gains after the remap on dyno: it kicks down if pressed fully at low rpm, so the dyno operator needs to ease in throttle until 2500rpm.
