When do you need larger injectors What power level do the stock injectors stop meeting the need? I have read some thread where people are putting down around 400ish and I never see anything about injectors but other people have 42lbs with similar mods. Are those people just being safe er what?

vids from the track are cam only, the red ls1 is H/C.. it was like 87 degrees out that night.. times SUCKED! i was running 7.5s@90.. shoulda been 7.2-7.3s@94-95..
the idle clip is a cold start.. it was like 30 degrees, car had been running about 20 seconds.. it hits MUCH harder once she warms up and smooths out..
drive it 50 miles a day rain or shine.. love it... get a good tune.
