My 1996 48 hp johnson came fro

My 1996 48 hp johnson came from sea level and now I run it over 2500 feet to 7800. The original jets were 55 type D. I believe this should be changed to a 53-D. Can anyone confirm this???

Also on top of the carb in the plastic carburetor cover was a jet #56-C. Should this be changed also and to what?

thanks
