I have 2.5 ton residential split unit, it said to be 400cfm

I have 2.5 ton residential split unit, it said to be 400cfm per ton , so it will be suppling 1000 cfm, when installing new duct work, do i need to have all supply vent total equal to 1000 cfm? What i am trying to do is because there is three rooms total 800 sqft 2nd floor. The air handler is far away from two of the rooms i tried to push a stronger air flow to the rooms.I am currently using two 10 inch flex duct from the plenum and use a Y to split two 8" flex ducts. Can i just leave it like this? Because one 10inches supply only 300 cfm, so i only have 600 cfm supplying, would this choke the system?
