Default speed limiter?

My 1996 Formula A4 is bone stock and i recently discovered it stops me at 118, do your cars do this? because its not your typical GM limiter where it just shuts you down, my car acts like its at the top of a gear and refuses to shift, just bounces off the limiter?

Did your car come factory with Z-rated tires? Because if not they put it speed limited to under 120 mph.

Do you have 2.73 gears or 3.23s? Check RPO codes in Glovebox for GU5 or
GU2

If you haven't won the race by 118, you've lost, that's all there is to it. And if you are winning, might as well be modest and shut it down once you know you're going to win. You can't trap higher than 118 on a stock car anyway, and by the time you can, you won't have a stock tune and you can remove your speed limiter then.

lol my car has 235's and it is just a limiter because its "hitting the rev limiter" at 4000 rpms, lol, nowhere near redline, so if i get even just a simple trifecta tune it will get rid of the limiter?

Yes, not to mention a little more power too.
