[Antennas] increased antenna bandwidths through a tuner, why?

Dear Sam,
You did not say what SWR you have at "minimum SWR". If it's 1:1, that's one 
thing. If it's not 1:1 then Chris has a point.
My guess is that the tuner has its own losses, which are often quite 
significant, and that could lower your overall system Q and efficiency, 
which would show up as increase bandwidth.
My "SmartSmith" Smith Chart program would allow you to model your antenna 
and your coax line and your tuner, if you have the patience to do all that.
