I have 2015 road glide. Just installed a screaming eagle breather and the vance and hines true duals with the cross over in the pipe. ( love the look) and I have a set of 4" Rineharts on for mufflers. I know I know I need to have it remapped but do I need to buy a power commander? I am not sure that is the proper name. Just looking for any type of input. Cause I really have no clue...
