Getting ready to install PFC on S4..
So as of right now I have just about everything I need to install my PFC on my S4 TII. one question remains though...
I plan on using 720cc and 1600cc low impedance injectors. Will I need to use resistors with low impedance?
and also, i only have a base map for the factory 550 injectors... how hard is it to interchange the injector size in the settings?

hey willub adjusting injector size is pretty straight forward. just use the correction formula. only thing youll need is to find your injector dead time or injector latency as apxei likes to call it. if u need help drop me a PM i install and tune PFC's pretty often.

if you have an 87 S4 you do not need resistors because they have a resistor pack stock. Only the 88s need to have resistors wired in.
and I have had best luck with 6 ohm 10 watt resistors. the stock resistor pack on an 87 is 5-7 ohms. i found that i had hesitations with 10 ohm resistors.
then again, a lot of people run them with no problems.
