A Stage 1 download will remap the WOT A/F mixture.

Your O2 sensors will take care of the part throttle mapping.

You could go either way. Just a DL will still leave it running a little lean tho. Using a PowerCommander will allow you to set the air/fuel to a richer level .

If you have no plans to ever do anything else to the motor, the DL is the cheapest way to go, and it'll work fine . :)

With the PowerCommander you can reset the engine timing also .

All in all , that's the way I'd go . I have PowerCommanders on both of my FLHTCUI's .
