Unless you plan on using 8x 525cc injectors(flat out, which would be close to the pumps max) then it will do just fine

Walbro = 255 litres per hour

525cc x4 injectors= 2100cc or 2.1ltrs per min x 60mins = 126 ltrs per hour.
525cc x8 injectors= 4200cc or 4.2ltrs per min x 60mins = 252 ltrs per hour.

Check it can do it at the PRESSURE that you require.

So about 5.5bar with 2 bar boost.
Anyone got a flow chart?

The ITP 048 is on its knees at 350bhp with that pressure, even though their sly advertising suggests its 500bhp capable. They will argue it is, but only on a NASP car. I had the argument with them... lol
