Tach problems....
My tach has been messed up sinse I bought my '90 RS. Basically, it reads super high. If I floor it, it jumps all the way to the right. I have installed an MSD-6A since I've owned it. Does anyone know the problem and the fix, or should I just try to hook the tach directly to my MSD? My 700r4 is fading fast, and a T56 is in the garage waiting to be put in. So I need the tach to work. Thank you

the truth about factory tachs...
they're kinda like hondas, they're great until you have a problem with it. In my experience, my money and time was well spend on an aftermarket tach. more precise, less worry and will work with aftermarket ignitions.
