First, your friend set you up with very nice equipment. It sounds like you want more air and vapor. Try the beyond vape Silo. It uses the same coils you have and is made by the same manufacture as your Nautilis, with one key difference: It has a larger airhole for more air.
One additional thought. If you are not aware, your nautilis has four airflow positions. There is a dial in the bottom of the tanks that turns and clicks in eack position (90 degrees between each position). If you haven't, play with it to get to the largest airflow setting.
