i jusr recently repowered from a carbed 350 to an efi 350 and the only thing that is wierd is the tach, i hooked my shop tach to it and the boats tach is about 1100 off (slower)from the shop one,
I did go to an electronic ignition.. I didnt think about that. Maybe it puts out a lot more voltage... Causing a wrong reading. Maybe adding a resistor?
