Looking for a Digital Tach
Looking for a Digital Tachometer for my FD. I'm pretty sure the Oem Tach is inaccurate right now, and I want to be a little bit for precise on my measurements.
FD has 118K on the Chassis.
What brands do you guys recommend?

Why do you believe the OEM tach is inaccurate?
It is trigger by the ECU w/5V square wave, which the ECU generates based on the crank triggers. As long as it is mechanically working, then there really isn't a more accurate signal.
Looking through Summit it seems there are a few digital tachs available:

It's just that when I'm accelerating the Car, the Car feels a lot faster than what the Tach is Reading. Same with Decelerating. I want Digital Tach to show the exact Speed in Numbers. Thanks for the Link!
