What are the biggest injectors I can run on the stock ECU w/ no AFC? And what FMU disk would be best to use w/ said Injectors? All opinions welcomed, I'm just checking out all avenues for my setup for next year. I'm just curious what the stock ECU can handle. And what if an VAFC was added, how much bigger would I be able to go on the injectors? Also what do stock ITR injectors flow?
Thanks a lot.

310to 370cc is the biggest probably you can get away with with probably a 8:1 or 6:! fmu

 

If you add an AFC you can idle 450cc injectors no problem. I have heard of people idling 550cc injectors using very low static fuel pressure. I don't think that is a good idea though. Stock R injectors are 240cc just like any other B-series injector.

 

Thanks guys! I appreciate the info.
