Should I show the max. allowed file size in an upload form?

No, not at first. Most of your users are going to upload files smaller than 128M anyway and won't care about the limit. Don't show useless information to them. Don't make them think. I am sure your UI ...

Should I show the max. allowed file size in an upload form?

I don't think you should show or accept 128 MB files via an upload form unless you're pretty sure your user have good speed. Even on 10mbps, 128mb file is 2 minutes of upload: it's a rather long ...
