High oil pressure after oil change??

Well I went the easy route first and tried the standard 51085 filter. It dropped the pressure 10psi at higher rpms. Kind of cold here now and could only get the engine temperature to 165 degrees. Still hitting 90 psi doing a burn out and about 80 psi if I get on it while cruising. Otherwise 50-60 psi cruising and 40 at idle.
