I'm have installed the Rinehart slip on muffler on my 09 FLHX vs the Scream'n Eagle. Now I'm thinking of installing the HD heavy breather air cleaner. It's not worth a $150 one time remap when I plan on more performance up grades in the future. Next upgrade will be the Stage III after the factory warranty.So I'm thinking of going with the Super Tuner or Power Commander? Your thoughts please. I'm new to the computer era on bikes so I need some ideas.
