There is going to be a delay w/ a stock tach, the signal comes from your pcm to the actual mechanism that moves the needle, moving parts will cause a delay. A shift light on the other hand takes a light via a signal directly from the pcm. There are no moving parts so no delay. Same principle as drivetrain loss. This completly normal, the engine is going to outrun a tach.
