Game center data

Hi..i want to delete my game data in game center. I already uninstalled the game and remove the data in game center. But the problem is when i install back the same game and connect it to game center my old game data was loaded back. Now i'm playing the new game without connecting to game center. So now i just want to play this new game and connect it to game center without loading my old game data back. Anybody can help me?? I already put my money in this game. So i want to keep my current account.
