Your Infobox template appears to have a fixed width of 300px...

At the top of the code: {| class="infobox" style="font-size:89%; width:300px; background-color:#FFF;"

Just change the 300px to a default to a parameter like this: {| class="infobox" style="font-size:89%; width:; background-color:#FFF;"

Then when you want to change the width of the infobox, just call it with the parameter set to a different width:

A good idea is to leave the Template:Infobox unchanged and make a copy of it called Template:Infobox_custom or a more descriptive name like Template:Infobox_witch and modify the copy. This way, if you really screw something up, you have something to reference that works. Don't forget to copy the /doc subpage too.
