Right now I have stock injectors and a 12:1 FMU. If I were to upgrade to 450cc injectors, would there be to much fuel there?

 

I dont think you need an FMU with bigger injectors and i think you need an A/F if you can do this on a 6gen accord. I need to know whether to go big injectors an A/F or FMU and missing link. I have a 99 5spd accord. I have a full turbo kit list that a guy ran on a 99 accord if you want to see it.

 

If you upgrade to 450cc injectors you will need to get something to control them like the afc hack. So yes if you upgrade your injectors you will have too much fuel. This question should be in the engine management section.
