At the expense of changing the unique tuning (Need for Speed: Most Wanted (2005))

Please tell me! If you put a winning unique tuning for the cobalt, if it to remove in the store( on a default to put everything), then will I be able to put it on another car or a unique tuning of a single ? Just in the battle with the Earl wanted his car hard, now I have a cobalt without additional tuning left, and the meaning cacati it on without this one prosranoe tuning.
