Which one is better?

 

huh?

 

Power commander (plugs into bike)


Motorcycle Dyno (bike sets on top of)

 

now that we've cleared that up, whats your question?

 

Well, if you just want your bike to sit still on a stand where you can rev the engine up and measure your horse power go with a dynomometer (dyno).

If you'd like to install electronic componentry that will re-programming your bike's stock timing and fuel air mix you want to get a Power Commander.

Once you install the power commander you can either use factory provided programming or you can take your bike to a shop that has a dyno to have a custom configuration (referred to as maps) created specifically for your bike. Most people go with the Dynojet provided maps, they have an extensive catalog. However, many also pay $$$ to have a custom map created specifically for their bikes.
