Twitter Update Plugin

Does anyone know of a plugin I can use that will change
” 6 minutes ago via You Are The Scene “
like that my sites name. I’m using twitter tools but the only down side i don’t like about it is that it reads and I can’t leave blank is
“New blog post:” I would like it not to read “New blog post” first then :m the title of my post. rather have a plugin that will read via my site name and the blog post title

any plugins out there like that.
