You should have a restrictor in there to match whatever the combined flow of the membranes is. My system runs dual 150 gpd membranes so the restrictor is 300 gpd. The flow restrictor is what forces the water to go through the membrane. If you run the system without a restrictor, you will be causing lots of water to bypass the membrane and very little to actually be going through the membrane. Why would you remove the restrictor?

If anything, you can use a restrictor that is less than the combined flow of the membranes, but then you are causing the membrane to flush less than recommended. So say you have a membrane and system that run 1:4 ratio of good RO to waste. If you use a lesser restrictor then you may cause the system to run 1:2 or even 1:1. By preventing the flushing though, you can cause the membrane to prematurely clog up. So it depends which you prefer - membrane longevity or wasting less water.
