Its a tuner, not a chip. A chip plugs into the computer and stays there. A tuner plugs into the diagnostic port, reprograms the computer and then you unplug it. The 87 octane setting is mainly for shifting improvements -- the mileage gain will be none and the power gain will be small. The premium fuel tunes are the power tunes. It will not work with 2005 V10s.
