Question about fuel injectors

[WhtMa71]

Yep. The stock regulator is NOT adjustable. You have to drill out the orifice in the J-tube with a higher flowing pump or you will have high fuel pressure and probably run very rich. An adjustable fuel pressure regulator will bypass the J-tube.

Whtma71, that's good answer. what's the cut off point for as far as boost on this set up? Can you go 18ish?

It all depends on your other mods. Turbo size, exhaust,and larger intercooler piping plays a big role. You might be able to run 15 psi on a stock turbo(not that you'd want to) with stock IC piping/exhaust but once you upgrade those you could only be able to run 12 psi.

Will larger injectors and a piggyback you can usually run a little more boost depending on how much fuel you have to pull.
