Ive just been reading back a bit and was wondering does anyone know why the cars left the factory with not so good power delivery/smothness, flat spots or sluggish throttle responce. I can inderstand resticting the BHP and torque for CO2 and tactically placing it lover than the V6's, but so many people have mentioned that even puting the mg zt on the r 75 improves it vastly.
