Update for Engine Control Module. Should I Update?

The BMW dealer says they have an update for my CPU and its going to cost me $140 plus tax. They say it will fix my idle surge I have on cold starts. I asked if it my tweak or make anything better performance wise and he said no it will probably take some out. I am like what?

What do you guys think?
