Quick question for the experts. I have seen some fluctuations in my Tach at WOT. Previous trip I was turning about 5950rpm and all over the revlimiter. My most recent trip I was turning about 6150rpm and just a beep or two on the rev limiter. Same load and setup. I have noticed this fluctuation a few different times. Maybe a tach setting? The difference is always about 200 rpms. Its on an 04 Merc 200 EFI. Any thoughts? Thanks, Jay
