MSD 6A makes tach drop
1987 GTA 5.7 TPI auto.
I installed an MSD 6A box with the harness adapter, easy install.
Driving along I noticed that my tach drops when Im 1/2 throttle or more.
Did I miss something on the install, my grounds are good, do I need a tach filter from MSD?

Re: MSD 6A makes tach drop
Is your tacho now fed from the original point or off the 6A tach output terminal?

Just from the original point, it doesnt mention anything about hooking up the tach output to anything.
