New membranes are always much slower than their rated GPD but it will pick up after a couple of days worth of running time. If it makes you feel better the slower it goes through the membrane usually means it is being filtered better. My unit suggests discarding the first 20 or so gallons of water with a new membrane as there will be some manufacturing residue in the first bit of water. As for tuning I just open the tap full blast and let it go. I have a 60GPD unit and even with full pressure it has a hard time getting the rated 60 GPD.
