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 .Thanks for the info, but i need some clarification. Being new to harleys, does the mms ean i need a power commander or just have a download put into the stock system.
With the PowerCommander you can reset the engine timing also .Ok. That helps alot. I think ill plan ahead and go with the power commander while its in the shop. Just in case i want to do more in the future.... Thanks for all the help.![]()
