Get an ALDL cable, download WinAldl and see what numbers are filling the BLM cells. The 'magic number' is 128. Higher numbers mean the ecm is having to add fuel, lower numbers mean the ecm is pulling fuel. You can increase fuel pressure to bring the BLM's down, but be warned that Multec injectors do not like higher pressure and will fail to open. If you log the BLM data, there are people on the board that can use the info to make you a chip and you will not need to mess with the fuel pressure.
I run mine at 45psi with a high flow pump. I also run a turbo with 10psi boost and 24lbs injectors. I would bet 45psi would be just fine. I agree with Cooter too, use Winaldl to make sure your injectors are not working too hard.
