I have printed PLA that low and as high as 220. I tend to run higher with the E3d. You can adjust flow in the slicing programm or on the fly with LCD. Also, make sure you are not dragging the filament. I had problems with filament drag, both from spool turning effort and as the spool got towards the tighter winds...from that.Things aren't always obvious and it does take some time to figure it out. You might also want to design a hollow cube as I described above. It helped me sort out some things.
