Playback tach ??

Any ideas on what may be happing?
I don't have a race pack.

On the Playback tach
1st gear is real smooth to 6000

2nd gear it falls back an sits for a bout 1 second (in slow play back mode)
then climbs slowly and "hops" a bit. to 6000

3rd it falls back to the same spot climbs slowly
from 6300 on it starts" jumping & hopping" real bad.

I don't know what this is the tach looks smooth when making the run
the car doesn't miss or pop and runs a decent MPH 122 IN D/SA
.

Any help or ideas on what is causing this would help, thanks.
