Hey all,
Do anyone know the size of the standard RS4 S injectors. I am currently running approx 190rwkw with a pfc, trust front mount, full exhaust and 12.5psi
However I am getting injector duty cycles of up to 98%
I have just replaced the fuel pump however was told that the standard pump was working fine ( I replaced it really for future mods) which made no difference.
Are the stagea injectors smaller than others? I was under the impression that the stock turbo would not max out the standard injectors, and it was only until you replaced the turbo that the injectors needed upgrading.
Cheers
Dave
