    That can be done - I'm sure. There are lots of computer tuners out there than will be happy to "tune" your car and removed the speed limiter. Just find a good one.

    I haven't had a chip or computer tune done in many years, so I can't recommend anyone right now. My cars are all stock, so I haven't been interested in a program change on them.

    D3 Cadillac appears to still tweak STSs, might want to get in touch with them. They are a bit pricy if you ask me though.

    That's the catch - finding the "good" tuner in your area.
    Check around for shops with dyno's - they'll need a dyno to make sure that they actually get it right.

    That's in the ball park. The place I like in Tulsa charged $450 for a dyno tune a few years ago.

    Remember, supercharger whine is bad for gas mileage!
