Has anybody ever experienced the same problem:

If I start up my stang in the morning, there is a 80% chance that the tach has about a 1 - 2 second delay compared to the motor starting.

I crank the motor, it fires up immediately. the tach still says 0 RPM. 1-2 seconds later the tach jumps up to the RPM the motor is running at. From then on, no more tach issues.

WTF is that?

Any help is appreciated.

That is normal.

Even if that's normal, it su#!$.

The strange thing is that the tach did not do that when I first got my stang.

Found out what caused this Problem:

To big of a drop in voltage at start up. Changing the battery solved the problem! Now the tach works immeadiately.
If you guys have the same problem check out with a new battery first.
