Default Fuel Injector Question

My car is in the dealer right now getting upgraded with k04's They asked me if I wanted the RS4 fuel pump and RS4 injectors. They gave me such a good price on the parts and installation i said yes. What I am wondering is should I just get the fuel pump and hold off on the injectors? Reason being is I want to run stage III software and I am not sure if the RS4 injectors will supply enough fuel for the job. I am also going to be using the 5 bar PFR .. Please let me know what you think.

You need to figure out whos stage 3 kit you're going to run before you do either, IMO..

Default I believe the RS4 uses it's own stock injectors

until it gets to Stage III. You should be fine.

Default You mean flow rates i think, and they vary with each kits injector choices...

Matching the injectors to the ECU tuning is critical btw. And the 5 bar may or may not be necessary depending on which stage 3 you select...

This is sort of my own stage III kit ... I want to run GIAC software but they don't make it for the TIP so I might have to use someone elses.. I just want the car ready for when that time comes..

Default unless you are going to get custom software or run ams/abt or apr software - you cannot run

just those injectors. You will be fine on your stock injectors and 4 Bar FPR.

Default Your stock software on RS4 injectors and 5 bar fpr is going to over fuel your

engine.
