Ok so after alot of driving around yesterday datalogging I had come to the conclusion that the 4.3L injectors were not cutting it. WOT PE couldn't get the AFR below 14.9 on the WBo2 at high rpm, VE table at 97% and DC in the 70's. Yes I know I could have put more pressure to them, but I figured I was getting up there in DC. So I slapped in a set of 61# injectors copied the injector latency table, flow from a 5.7 bin, and backed the FP down to 13psi. Now I'm globaly lean without changing my ve tables. is there something I'm missing here? going from 46# injectors @ 15psi (according to the calc they were running 49# at that pressure) to 61# at stock FP should have made it rich doing the math, or maybe I just don't understand. So now what do I do? lower the injector constraint or raise the FP back up?
