Will 550 injectos work with out fpr

[cramec2]

I want to get larger injectors for my 95 tsi. I just installed 16g and walbo 190 with re-wire kit..Do I need fuel pressure regulator with 550 injectors.

No, but you need some way to control the injectors.

I have AFC2...So I will need FPR for 550 injectors..?

 

[spoolup]

no, the stock FPR will be fine for your setup.

The AFPR is needed to control fuel overrun issues during idle and deceleration when using a big pump like the 255. So, no, you don't need an AFPR for the 190 and 550cc injectors.
