They're out to get your money. The cat failed and they're on the hook for the darn thing. That is what the law was written for, to protect consumers and to compel the companies that make cars to be accoutable for certain failures. The failure of the cat is their responsibility, the maintanence is yours, are you willing to accept it? If so then I would consider what they suggest, have the tune up as a matter of preventive maintanence. Where you have that done is up to you. And it is within the realm of possibility that the cat will fail again if something is not done.
