2. Power Commander V

Of course, if you’re going to make a motorcycle breathe easier, it’s best to give it a revised air/fuel mixture to extract the most power. This is where the Power Commander V comes in. Also provided to us from Brock’s Performance, the $399.95 PCV is less than half the size of the Power Commander III, with more functionality. While the capabilities of the PCV are far greater than the capabilities of the Grom, it’s nice to know the PCV is able to map each individual cylinder in each gear on a multi-cylinder motorcycle. It also allows the user to adjust timing +/- 20 degrees, no longer needs a 9-volt adapter, has a built-in, two-position map switching function, and even comes with pre-installed street or race maps if you buy it and an exhaust system from Brock’s.
