Bone stock LQ4 6.0l Turbonetics 78mm speed density tuning, changing to Deatch 60lbs (at 43 psi) injectors and I'm not totally sure how the best way to set my system up. Whats the best fuel pressure setting 58 psi vs 43 psi and why? Set the IFR table at calculated flow rate for the psi across the board with boost ref? Set fuel pressure base psi with or without vacuum signal? Anything else I should change for the injectors before initial startup?
