Running about 14PSI, seeing a bit over 1500kg/hr on my stock longblock. Using the Lightning MAF in a draw-through setup, it flows about 1700kg/hr. If you are using a blow-through setup (MAF after blower) you won't get quite as much out of a meter in a draw-through setup.
For comparison, the stock meter pegs around 900kg/hr.
The SCT 2400 is my next meter once I put the remainder of my parts on, it flows up to around 3,000kg/hr.
