Sounds like the limiter has been removed. The reason for the 108 limit was due to the fact that it is slightly under the speed rating for S rated tires(rated for 112mph), so if your car can hit 140 the PCM has already been reflashed.

I'm not sure about the sixxers, but I know that the Z28's came speed governed at 108 mph if they were not ordered from the factory with Z rated tires. I'm not sure if Z rated was even an option for the sixxers, so I'm assuming that they're governed as well. If you want to take it off you'll have to get the PCM reprogrammed, either professionlly or you can utilize the Hypertech power programmer, but it's kinda pricey.
