    Is there any company or organization out there that makes an after market
    computer chip or reprogramming for existing ship that will remove the top
    speed lockout?

  2. AFAIK, you can take your car to the top of a big hill and go down the
    hill as fast as gravity and your lead foot will take you. I'm not sure
    I even want to ask why you want to exceed 130mph (the top of the speedo
    on my SL2) in a Saturn. Stock Saturns don't weigh very much and will,
    almost guaranteed, show the stress of excessive speed through extremely
    unstable handling characteristics. If you have the pedal to the floor
    going down the highway, thats probably as fast as the car goes. You
    might be able to eek out a few more MPH from a MT because of the
    different gear ratios.

    There is a rev limiter to prevent the engine from tearing itself apart,
    but that isn't the same thing as a "top speed lockout", or a "governor"
    as they are sometimes called.

    Why? The factory governed speed already exceeds all posted legal speed
    limits. I dont know where you can drive legally at those speeds other
    than the Bonneville Salt Flats and I doubt it will peek its top speed on
    a quarter mile track. I dont need morons on the road zipping by me at
    100+ miles an hour. From the sound of your post you need to get the
    "rice" out of your system and drive like a normal person.

    'Richard Hornsby' and 'Blah Blah' are correct, keep high speeds to the
    track. lest we forget high ticket fees, possible jail time, causing/being in
    check out if you want to race around. Might I also suggest
    taking some classes, you probably can't handle your car above 100mph.
    now to your question. No, the Saturn ECM is a proprietary system, it is
    encoded with a special electronic key, that no one has but the folks in
    Springhill, TN. there are reported ways around it, but most people wont tell
    you how to do it, purely based on the amount of time they have taken to
    figure it out. They don't want to tell people who don't want to take the
    time to figure out how it works to do it.
    so, take the coffee can off the back of your car, put your stock intake back
    on, and keep it to the speed limits, or take it to the track.

  5. Road America. An S Series car in race trim can bump the 124MPH limiter.

    For folks who run their S-series cars in SCCA Improved Touring, getting the
    speed limiter moved/removed, and raising the rev limiter to around 7k is
    pretty much required. There are several folks over on the forums that
    calim to be able to move the limiters around. go to
    and visit the PCM forum - should be able to find the information you

  8. Once I drove my SL2 at about 108mph just to see what it was like, on the I-5
    in central California. The wind drag noise got real loud and it felt kind of
    scary (and yes thrilling too of course). Handling wasn't bad at all but I
    was a little reluctant to bump it higher.

    And yes I did get ticketed, though it was later on in the journey, for going
    86mph (this was before the 55/65 max speed limit was lifted).
