Hmmm...that depends on where your "powerband" is. For instance, when buying a turbo kit, you should buy stage 1 for torque and stage 4 for h.p. This is because lower rpm's kick out more torque with each revolution whereas high rpm's kick out more h.p. This is why I have a front chainring ranging from about 25 teeth to 45+ teeth. I have to have a wide range in order to make it off the line.
