I have a 1990 175gt. I have one coil that wasn’t firing. I have the coil to put on but I was wondering how much it would improve the motors performance. I have it on a 1990 ranger 481 and I’m running 55 at 5400 rpms. I know the motor says 5800 is where the limiter is set. Just wondering. Can’t take it out right now I’m having the seats redone.
