Benifits of ECU Remapping

ECU remapping will not only improve the engines power and torque figures, it will also sharpen the throttle response and widen the power-band. This will make the power delivery a lot more linear, which in turn will make the vehicle feel a lot livelier to drive and the engine more flexible.
