As far as I am aware of...NO. But that is, if you use one of those chip boxes that you can restore the info back to it's original status. BSR,the inventor, uses this type of chip box to chip new cars. Then again, I heard there is a possiblity that Audi has put in an electronic sensor that detects when the engine has been modified. I guess it depends how cranky your audi mechinic is...
