My BJ8's tach did the same (though not quite as extreme). After I calibrated it 
it has been spot on at all temps and speeds.

It's in my BJ8, so it's electrical. 


Yup, overdrive on at 65mph.

Mechanical or electronic tach?

I've noticed that when I drive to work in the morning when it's cool 
(50-60F), my tach shows about 2500 RPM at 65 MPH. When I return home at 
night when it's warm (80+ F), my tach shows about 3000 RPM at 65 MPH. 

Any ideas about what's going on? 

thanks, 

Tom
