Latest updates. I maxed out my fuel injectors (550cc) at 400whp mainline at 5200rpm. Because of the increase in boost (7psi to 12 psi at 5200rpm) and my fuel pressure dropping to 40psi, injectors are max out. I'm going to get DW 1000cc in.
Also I'm thinking of getting a fuel return system on the car. What do you guys think. It's troublesome but I'm not sure if I can get away without one.
Thanks.

For sure your gona need a fuel return system at 12lbs, I’d recommend cj motor sports, thats what I installed on my z, plus the aluminum fuel hat from cj also. Your gona need a fuel pump relay kit (spal kit)also if you don’t already have one.
You might even want to upgrade your fuel pump while your in there, walbro 450maybe, especially if your gona be going higher then 12lbs of boost, not sure what your using right now for a pump? Or fuel?
I used Bosch ev650cc injectors at 12lbs but iam switching to e85 this year so Id1050s now.
