bigger injectors

[jevrem]

I am interesting for bigger injectors I buy, they are 440cc at 3 bar and the stock fuel pressure is 4bar. Does that make a problem?
Or I must by fuel pressure regulator to set fuel pressure at 3 bar. And if I set this pressure at 3 bar, can ECU make some fuel adjustment to achive wright A/F ratio.
Thank's

034 motorsport do a FPR for 440 Injectors...You will need remap for A/F ratio to be correct
