    Those cheap devices they call "chips" that connect to the IAT sensor are not real performance chips. A real performance chip tunes the ignition advance, changes the shift points and firmness, adjusts the air fuel ratio for more performance at heavy throttle and more economy at cruising speeds; and comes pre calibrated for each model vehicle. The device you have only makes the fuel mixture richer; regardless of whether or not it is needed on your model. This device will reduce your fuel economy, carbon up the engine, and increase the emission levels.

    I recommend that you return it to the place where you bought it.
