Hi jlew715,
The Ender 5 Pro is running a lower filament temperature what is the nozzle temp @ ?
Do you have a 0.20 nozzle by chance ?
Did you use the variable layer height option already on this part ?
If you only have .4 nozzle you can try something like this and see how it works out.
Let’s see if you can get the quality needed on this part you are the 3D test pilot 
Keep us all updated
