Yep. You'll need two tools different tools and a thumb drive. One of the tools is the save editor and the other is a utility for converting xbox saves.

You can find the save editor and some info on how to use it here.

There are a few options on the other, but I recommend Horizon. Modio is the one that you'll see referenced the most with regards to ME modding, however that tool only worked once for me.
