cneuy,
Yeah basically the tuner will load every time you fire up the game. When you press start from the main menu you see the game telling you loading environment, checking tuner set....something like that. So yes basically it loads every time you start the game. What your seeing in the file management screen is where the tuner set is saved to. Now if your feeling like the tuner set isnt loading properly you can go in there every time and load it manually.....or you can go in there an delete it if you ever feel like doing that. But, if you delete it you will disable a lot of the features from the patch and you wont be able to play online. Plus if you delete it - the next time you fire up the game it will just prompt you to download it again.
