What does a Power Commander do for a Harley?
A Power Commander allows you to remap your bike’s air/fuel ratio to be optimize for your aftermarket modifications. – It adjusts the fuel injection to optimize the fuel/air ratio in accordance to the increased airflow and modified power delivery dynamics.
How much HP will a power commander add?
The Power Commander is a tuning tool to adjust fuel, and on some models ignition timing. Just adding a Power Commander to a completely stock vehicle usually does not increase peak horsepower. It usually will improve drivability, throttle response, and mid-range horsepower and torque.
Can you put a power commander on a carbureted motorcycle?
They accomplish the same thing which is to achieve an ideal air fuel ratio when something is changed on the bike (exhaust, pod filters, etc.). If you have a carbureted bike then the power commander is not even an option, if you have a fuel injected bike the jet kit is not an option.
Can a Power Commander hurt a motorcycle?
Can a Power Commander damage your bike? It is possible but not likely. A Power Commander gives you the ability to adjust your motorcycle’s air to fuel ratio, which means you could set this so the bike runs too lean. However as the Power Commander can’t send any current to the ECU it is very unlikely it will damage it.
Can you tune a motorcycle without a Power Commander?

For many riders, an exhaust change with no Power Commander can lead to a loss of usable power.
Will Power Commander fit any bike?
No. The connectors are different for each injection system on each bike. In theory you can snip the old connectors off and wire up new ones. Not sure it would work on the two bikes you describe as the R6 has 4/8 injectors (so four plugs), whereas the MT-03 only has 1 injector (So one plug).
Do you have to tune a motorcycle for an aftermarket exhaust?
Newer fuel injected bikes when equipped with a tuner are significantly easier to tune. With modern fuel injected engines, re-tuning for an aftermarket exhaust is largely optional.
Is full exhaust better than slip-on?
The slip-on is the better option for those on a budget and only looking to enhance the sound of the bike while shedding some weight and increasing the power slightly. The full exhaust system, if you have the cash to spend, will deliver significant performance gains as well as a powerful sound.
