Just got my Shurflo (Booster) Pump today and conected it to my system.... What a difference it makes

Pumping through the RO at 4.75bar 70PSI and getting 7 on the TDS reading...
Hopefuly now I have got some good pressure I can fill the tank up quicker and it will make to RO run better aswell...
I notice that their is NOT alot of water waste either.
Does anyone else use a Booster pump? and at what PSI are you going through and what is the TDS
