Hi everyone,

I'm going to be fitting my supercharger in the not too distant future and I was considering upgrading my injectors whilst I had them off the engine. I'm not going to be upgrading my ECU just yet - it's in the to-do list - but my question is: Will the stock ECU able to run 550 cc (high impedence) injectors without issues or would it be better to upgrade the injectors once I have upgraded the ECU?

Thanks!

In my understanding, you won't even be able to run 315cc injectors without running into idling problems.Stock Ecu can only compensate 15%ish (285-290cc injectors). I am currently working on a 300cc 3rzfe injector swap with an FMU to remedy this very issue..
