Why does my car seem to hit a rev limiter around 5800 RPM in first gear and closer to 6200 RPM in all other gears?
The factory tachometer in these cars is slower than the engine is, so when accelerating in first gear at wide open throttle, your tachometer cannot keep up with the engine RPMs, and is actually a couple hundred RPMs behind when you first hit the rev limiter. Because it takes longer for the engine to get that high in other gears, this shouldn’t happen. Since this isn’t really a problem, there’s nothing you can do about it other than practice. With some practice, you will learn to listen to your engine and know when you’re about to hit the limiter in first gear.
