2002 lq4 6litre injectors maxing We have transplanted a 2002 lq4 from a 3/4 2wd with 3'' dual exaust and thumper cam, no other mods.i have recorded a log of data and noticed that around 5600rpm the injectors are at 99% and fuel pressure is at 60psi, what size is the stock injectors? and what size should i use if to small? are the stock that small that only the small mods that i made have pushed the injectors to the max?

Iirc lq4 have 24 ish lbs injectors. Your duty cycle sounds about right with a cammed motor on stock injectors. Any plans for FI down the road? If so may think about doing #60 now. And if it matters my old cam only ls1 was seeing 120% injector duty cycle.
