Right now I am running FI non-res CBE with no other modifications and the drone is definitely there, but I don't really notice that much anymore. It really just depends at what speed and rpm you are driving. If I am in 6th gear cruising at 65 or 70, its pretty quiet. Louder than stock, but quiet. If you pass someone, you will hear for it sure. But to answer your question, I would bet that you will still have quite a bit of drone with non-res CBE, especially with the HFC.
