First, back up your save, because you'll need it for this process. Take your save and open it in a hex editor. When you Ctrl+F for the value you're looking for, all of the instances of that value will pop up. Edit the first instance. Rehash/resign, transfer it back into your 360, and test it out. If it didn't have the effect you want, delete it, copy a save from your backup, and start over, only this time edit the next instance. Test it. Rinse and repeat, going down the list of instances, until you find what you're looking for. It's archaic and time consuming, but it's the most effective method you could use.
