I was reading in a issue of MXA that the YZ40F comes with 2 maps from default. Is this true, and once I plug my power tuner in, will I have the ability to pick the other factory map? I can't find any information about this on Yamahas website or anywhere else. In the MXA magazine, they said that the 2nd map was the overall best for a good portion of the people. Can anyone give me the particulars about this map and what it is setup to to different than the first map?
