Yea, it would require going into a custom tune, I just went through my options and found none. I was looking for this back when I got my car in 2010 as well and didn't find it.
Mine seems to go off when I am already redlining or so close that I can't react. It would be nice to get it to go off 500RPMs before red-line.
