only because you have to break the seal. but on some cars the chip can be accessed without breaking the seal, and can be reprogramed. Does anyone know if the tiburon 2001 can be chipped without breaking the warranty seal?
btw, I know there is a place in San fran that will do chip it for $100 flat, and if they can they will try to not break the seal. but I cant remember what the place was called.
