So if i was to get the ECU chipped or mapped to bring the power band down would this help the car pull better on highways when you go to over take someone, instead of it taking too long,and pulling away from the lights in the city or would this just be pointless cause it would be canceling out the purpose of changing the diff in the first place? If you get me!
