Tune on these lly in stock injection more then the bigger injectors ones. I have a generic 100hp tune in it max 20* timing right around 2000uds I have a fuel knock which I kinda figured would... I can sit in there and tweak till I get it but the duration on 30% over v's stock how much should I cut back on that and mm3 where should start to cut on that?.?... thanks for any input as soon as these roads dry I'm going to do some more testing for sure


Thanks
