RB tach not reading right??

[Yellow4g63]

I Have the RB 20 tach into my KA cluster and reving the motor out I noticed it dosen't hit fuel cut at 7500 but goes in deep past 7500. I took it to as far as 7800-7900 before I let off. This is neutral reving not road driving. Anyones else have this problem?

the rev limit is usually higher than redline, also stock tach's are usually off by a couple hundred RPM.

What "problem"???

WHEN MY CAR WAS WORKING RIGHT IT WOULD GO PAST 8500 WITH NO LIMITERS.

Thats a problem for me I don't have aftermarket valve springs yet.

JUST DON'T REV THAT HIGH.... I DON'T HAVE ANY AFTERMARKET VALVETRAIN PARTS EITHER.

I'm goin to hook up a revspeed meter to it and see what it really revs too! I just don't think it's really goin to rev that high!
