What the TUN label indicates

The TUN suffix identifies this catalog filename as a tuned variant. It does not, by itself, specify the modifications or their effect on driving. The related 89663-02482 identifier provides the calibration reference, but it does not confirm that this file is an original Toyota release or establish a specific application.
