I didn't know that Fred was messing with them like that. I must of been working. On a side note, I have been researching the different gamesaves online and have found that it isn't hard to increase your stats by insane amounts. Wouldn't that get you banned from XBL if you were facing online ur and did a crazy amount of damage?
It is a violation of MS' ToS and can get both GT and console banned at MS' discretion.
