Another issue no one has mentioned is everyone's favorite (NOT!)- e-throttle. If there is an actual sputter, check your fuel. If it's just bogging down, it's the traction control/ESP suite. In order to preserve axles, it cuts the nuts off of the engine. Really. It's also to help you in low-traction situations, so you don't spin the tires- Mark W.
Power band is above 2K rpms. If I'm passing, I downshift two gears many times especially if I'm in sixth gear. Sometimes when I'm in fifth. I travel a mountain pass a lot where I have to be in third in order to maintain good torque. It is something that has taken some getting used to in my jeep but have had better results after adjusting my listening ability to hear the rpms without looking at the gauges too much.
