Paxton 6 psi pulley
69# injectors
1 Walboro 450 pump in take
Stock fuel lines and rails
Max out around 775-800 crank hp (600-675 whp)
Stock bottom can only handle around 6psi

More than that then you need bigger injectors, twin pumps/bigger pump, bigger fuel rails.
A boost referenced pressure regulator would be helpful.
Who built your engine? They should have an idea on injector size.
The tune will determine amount of injector pulse
