My current mods are AEM cai, ETS 4 intercooler, ETS LICP, Nisei UICP, RRE test pipe, RRE catback exhaust and AMS fuel rail and it tuned. Its knocking(stalling) above 3k rpm in 3rd 4rd gear. Is it because injectors are maxed out?

 

Thats weird? Sorry wish I could be of help. Have you checked your charge pipes and made sure they are secure? If your injectors were maxed out I would think you would be informed of that during your tune. Have you raised your boost at all?

 

You have to tune with different injectors.

 

how much knock are we talking about, and what are your injector duty cycles at? Without looking at logs, the people you are asking to help you are shooting in the dark. Could be your fuel pump going out, a bad relay, or anything of that sort.

 

if you put in diff injectors and not tuned for them, your car will not run right at all!! i recomend that you don't drive the car at all until you get a tune for them. other wise you might blow your engine.

 

Your maxing out your stock injectors with those mods?

 

I doubt you're maxing out your stock injectors. IF you put in different ones, yes you need to retune. You'll have to first start by changing the scaling.
