<FONT size=2>I have a '87 Mustang GT. i got a auto gage tach. i also have a 6AL MSD box already installed. I put the tach in theMSD box. Do i need a tach adapteri get the right reedings on the tach. </FONT></P>

 

you do not need an adapter if it is working properly. MSD is copatible with almost Any tach.

 

i seems to reed a little high through 4000rpms but from 4000-7000 it drops .</P>


those readings are on my stock in-dash tach( i know this one is off.)</P>
