It was friday night or better said, saturday morning(4:30am) and i was driving home. There's about a 12 mile strip where it's like a dessert, so I took the long way home and decided to see how fast my car would go. It went up to 120 and didn't move from there, why?? My first mustang hit the 150 and kept going a little more, and so did my second mustang. Both cars were mildly modified like exhaust and cai and gears. What will I need to remove the speed limiter from this car??
