I have about 1000 miles and I'm trying to make sure to break in the engine trying the different modes and I'm confused. I've noticed the different modes change the shift points so there is better fuel economy in diff gear but going the same speed. I'm confused about sport mode. Will it shift for me or does it just have a governor. It would seem to me that it red lines and auto shifts while accelerating but I'm not sure. Does anyone know exactly how the shifting works in the diff modes?
