Chickenman Posted July 14, 2015 Share #61 Posted July 14, 2015 Factory Tachs can be notoriously inaccurate.. but they do have an adjustment on the back. I would confirm RPM's with a second digital Tach. If they match then you may want to consider adjusting your dash tach. What ignition are you currently running?
