Impressive! I know a lot of car manufacturers put speed limiters in there because they don't install Z-Rated tires on their cars from the factory, and they don't want a 'liability' because of that. I stand corrected!

well lets see know, I do need a tune up and some moe things done to the car and some tiires. If I do all of this, I might be able to do the Z-rated limit. That would be nice. Then after that I will never speed again......

Why would my car come equipped with Z rated tires from the factory yet the ECM shuts down my car at 116? Doesn't seem to make much sense if you ask me.
