Default Apexi vafc dsm 450s' t3/t4 .60 trim 10-12psi=300hp?

Right now I'm running a t3 .60 trim nissan turbo, management is the vafc walboro 255 intank pump and dsm 450s'. Car's putting down 250hp at 10psi. I want to take it to 300hp at 10-12psi with a t3/t4 .63 trim with the same fuel management. Is it posible to run the bigger turbo and put down 300hp with the same
fuel management? I also have an adjustable fuel presure regulator. Don't slam me on my set up, just let me know if you've seen this working out for someone. I have the distributor retarded 4 degrees.

I wouldn't do anymore to it and leave it where you are at. You will blow that terd up with the afc. I used an afc for a while at 9psi and we have the same engine. I also had it retarded 2 degrees at the dizzy and i also had a btm set at 1. I GOT MY MAGNIFINE GLASS AND I HAD REAL TINY DIAMOND LOOKING FLAKES THAT WAS SUPER HARD TO SEE imbeded on my plugs so i had some det. I was running low 13 afr's cruzing and high 11's in boost. As soon as i saw that dang little flakes i shut that terd down. Yanked the afc and btm and sold them the next weeekend. I bought the 600 dollar kit from xenocron and it has never ran so dang good even with the base map they sent me. You are treading a fine line i believe anything past 9. My afc was set near the same settings stated in look here first forum on engine management. THats my two cents. Good luck
