i had a question about my Autometer Tachometer. I have one in my 94 Z28 and it reads a little different than my stock one. Is this normal? My autometer tach will read 5000 rpm's but if i look at my stock one in the dash it will read something more likek 5200-5300 rpms. Just wondering if it is off b/c it is a little more accurate. Thanks Guys!

 

That's exactly right. Your aftermarket tach is most likely right on the money and it shows different from your stock one because the stock one is off a little. No worries.
