Hello, I have a L33 out of a 2006 truck. I used the injectors out of a 2008 H2 6.2. P/N 12580681 I believe. We're having a bitch of a time trying to tune with the gen4 injectors. Can anyone tell me what I would need to do or how to do it to be able to scale the gen4 injectors into my gen3 PCM tune? I'm not the tuner for this project, my friend is. He's mentioned many things like injector scaling and injector offset that I'm doing my best to understand. I'm trying to find any information I can to pass along to him so I'd be grateful for any help, thanks
