im gussin hes talkin about your injector duty then man with him sayin in percentages, if he was on about your car on idle and injector duty been 6.5% sounds a bit high but will check mine tonight and see what my injector duty is on idle. because you need to worry if your car is on full boost and your injectors are maxin out not gettin anuff fuel in for your set up makin the car run lean. someone correct me if im wrong... p.s i dont think your car will be maxin out the injectors tho
