and where are you getting the RPM signal from?

If you're not, try tapping into the white wire with a blue tracer coming out of he ECU.

You never had problems with MegaLogViewer before using that wire???

 I was using the tach signal. It was way off. Tony told me to use the white wire with the blue stripe coming out of the ecm and it works perfectly. Didn't have to mess with any settings.
I don't even know that there are settings for RPM adjustment???

Be a good Huh? for Tony.

Is MegaTune displaying the RPM correctly?

I hooked my laptop up to the MS when I had it on the dyno and it would read the rpms fine in Megatune until about 6-7k rpm then lose signal but when the bike dropped back to 6-7k it would regain the signal?

Interesting. Try putting a 10K to 20K resistor in line with the sensor, that often helps.
