    Tune for better MPG on Stock 02 T/A?

    My wife has an 02 Trans Am A4 that I would like to use tuner to give her better MPG. I am still new to this so other than fans, and shift points I am at a loss. I have a NGK wideband ready to go. Any help in what to adjust would be great.

    changing the low TPS shift points are a great first move! some people force their cars to run lean, i dont recommend it but it works.
