Motorcycle Repair: Power Commander, air fuel mixture, power commander

Question
Mike, even if it is tuned on a dyno will the power commander alone make a difference?  I wanted to start with that and then maybe continue down the upgrade path.  Thanks...

It is fuel injected...
Mike:

If I bought and installed a power commander on my 02' Road King, what would it do?  Could I install it and tweak it myself and would it be worth it?

Thanks...Roland

Answer -
Carb or fuel injected?
Mike

Answer -
What it does is change the air/fuel mixture in different RPMs. You can get it close, but the best way is to do it on a Dyno
Good luck and happy riding

Answer
Yes it will make a difference. When your bike came from the factory it was a little lean so it would pass EPA standards. Any changes you make would make it run leaner, so the power commander will bring it back to where it should be.
Good luck and happy riding
