Bigger injectors or regulator?
To compensate for the increased airflow from an intake and exhuast system, what would be the best fuel upgrade? Bigger injectors or a pressure regulator or both?

pressure regulator. Bigger injectors aren't needed unless you go F/I, or Nitrous.

Dude, it wont make that much of a diff getting a fule regulator for intake and exhuast. You're ecu will compinsate for that to a point. You'll just be running rich.

Then at what point would you use a regulator?

with cams, headwork, or FI. but you could use one now, but to remove fuel. if you drop the pressure by 1 or 2 psi at a time, you can pick up an hp or two. the factory tunes cars "safe' from the factory, read:rich. if you lean it out just a little, you can get a little gain, but dont go too much, or youll get detonation. and high octane would be a good idea if you lean out your fuel.

Hey got a quick question, since the D17 is a returnless fuel system would I be able to use an aftermarket FPR? I know Comptech makes a universal one, but not sure if thats only universal for returned fuel systems.
