The Power Meter will time sprints, and allows you to map the boost on a Speed factor using 4 separate Boost Control channels. Each channel can be get for not only different Boost Levels, but different Gain settings too, which controls how the turbo spools up.

You can also display the boost as a graph allowing you to see how well the boost is held and where it drops. You can also record a certain amount of information.

There are also additional Data channels which can be used to monitor other factors, which can be graphed too.
