I think I remember reading an issue with this, but could not find anything when I searched. I have a 93 Formula M6, the factory gauges went to 110 and the trip odometer did not work, so I swapped to a cluster from a T/A that goes to 150. everything works besides the tach, it just kind of twitches around 500 rpm whenever the car is running. Is this an issue that could be resolved with a tune? Did I buy messed up gauages? Any insight or links to insight would be appreciated.
