Inaccurate Tachometer?

I went through and cleaned some electrical connections a while back and that seemed to help slightly (maybe 50 RPM?). One of my trailing coils is pretty crispy so it is being replaced and maybe that will amount to something. I'm pretty sure this is a combination of the accuracy of the stock speedometer/tachometer and the poor charging system in the RX-7. The latter is fixable, the former, probably not so much unless you switch out for aftermarket.
