Tach and other gages recalibration
Is there any way to calibrate my tach and other gages after reinstalling them? I did not take the needles off of anything but the speedometer but the others are all electric. Thisw is on my LG4 powered 86 IROC.

Thanks!
Mark

Could it be something as simple as that? I have been driving with a tach that has been off since my MSD installation. I have been through many a headaches trying to figure it out.
