So I have a 67 RS w/deluxe interior, non-stock console gauges (factory), and the stock tachometer, with An MSD ignition system and 6AL ign box (non digital model) and my tachometer is bouncing all over the place... MSD said to turn of the in-line filter, which I did, but it lags and has no accuracy what so ever! Any ideas on what it could be??? Do I need an aftermarket filter that MSD Sells??? Or an I just missing something simple? Thanks for the help!
