Posting location and what limiter you are talking about would be a good starting point.
Welcome to the forum mb
Not all U.S. vehicles are goverened. I know of several w/o a govenor, and many with govenor above 250KPH (155mph) . Corvettes, some of the hemi chargers, and several cadillacs aren't goverend, along with some imports just to name a few. The Z06 corvette and one cadillac have top speeds in excess of 200mph (aprox 330 kph)
Now how to change the limiter is another question. In some cases it is a piece of cake, for instance on my Silverado diesel, with a diesel programmer such as the diablo preditor, I can set the limiter to anything I want. Factory is set to 99mph, resetting it to 115-120, which is what it is capable of with the proper speed rated tires is not a problem. Now do I want to drive 7000 lbs. of good old detroit iron down the road at 120, hell no!, but the 99 mph limiter is way to easy to hit when passing a long truck. you might want to look at a few of the diesel tuners and see if any will let you change the limiter.
