    Not really brother, but disconnecting the battery helps a bit. Also, throttle calibration helps acceleration response time.



    Throttle calibration can substantially improve throttle responsiveness over "factory standard." Many people notice what appears to be sluggish throttleresponse or a "dead area" at initial accelerator depression. Throttlecalibration can take care of these.
    1) Insert ignition key and turn to "ON" (not start).
    2) Wait for all idiot lights to go out. Check Engine Light may remain on.
    3) Slowly depress the accelerator pedalall the way to the floor.
    4) Slowly release the accelerator pedaluntil it's all the way back up.
    5) Turn the ignition key to "OFF".
    6) Start the engine.
    Most drivers notice an immediate change in throttle response, but depending on your driving style, you may need to repeat this procedure periodically due to the computer's adaptive programming. You likely need to repeat this procedure any time the battery is disconnected.
