I see you got 24 pound injectors? Why not just go 30 for safety sake,and tune them down with your adj. regulator? Just curious?

That's not my personal combo, just one that I'm suggesting. I don't have that kinda money, lol.
Injectors reach safety limits at about 100psi. A good fuel pressure regulator might be adjustable up to about 60psi. There have been countless tests that show 500hp can be made on 24lb/hr injectors, and the combo I suggested is probably somewhere in the 400hp neighborhood. 30lb/hr injectors would probably be in the list if I thought the combo would make more than 425-450hp.
If you were to use 30lb/hr injectors with 400hp, likely the fuel pressure would be lower than stock, and the lower your fuel pressure is, the less efficient fuel atomization is. If you get to 20psi, you'd basically be squirting liquid fuel. The more pressure you have, up to reasonable safety limits, the better the spray pattern and fuel mixing is going to be. The result will be a more efficient burn, more power, better fuel economy, and greater reliability due to a more reliable burn, and the computers ability to tune.
