I use a RMI for engine monitoring, Specifics,,,, on the mag check on right mag everything is normal. On left mag rpm indicates 1/2 but the engine doesn't feel like a loss of power of this magnitude. So I asumed this was a indicating problem. When flying the RPM is erratic, on right mag it reads 2300 rpm and you get a mag drop with a rise in egts on all cyls. If you go to the left mag RPM is half with a rise in egt on all cyls. The mags have about 250hrs since ovhl and they are slick mags. I think they are 4070series.
