Since I bought the car, maybe 5 months ago, I could always rev my first gear to 6200rpms no problem before the rev limiter kicked in. Just randomly a month ago, my rev limiter seems to kick in around 5600, not 6200. I know people say the tachs on these cars can be a bit slow, but wouldnt it be slow from the factory? Mine seemed to be very accurate until a month ago. Is this normal for it to "get slower" randomly?

Maybe I just need to buy a shiftlight to answer my question...

 

well??
