I am running the C sp and VRinsight MCP Combo. Everything has been working but now the plane is chasing headings and LNAV to the point that ATC is questioning what is happening. Anyone else have this?

Do you mean the aircraft is banking left & right without settling down? If that's the case try disabling turbulence. (or suppressing it if you use fsuipc)

Yes I will try to disable.
