Hi Guys,

I have been trying to fine tune my fueling for my 5.7 Hemi with a SRT 6.4 Cam. I have gotten fueling close, about 5% either way. When I try to get it close to 0% fuel trim I cant. I'm hoping someone who has experience with tuning the dodge Injector pulse width properly chime in, I have rescaled injector tables to get it all working, and so far so good...but I feel I'm missing something rather important when correcting the fueling.
