Stock Injectors Maxed Out?

I was seeing if this has happend to anyone have a stock 5.3

Headers full exhuast and K&N air filter. Went to the track made a couple of passes had HPtuners scanning showed my injector duty a 100%-110% in the higher rpms. Do I need bigger injectors? I was thinking stock injectors for stock motor right tune is not stock? If I need bigger injectors which ones do yall recommend? I will attach my scan files.

Would 42#ers be to big for a stock motor. I plan on spraying it with a wet shot and putting another cam in it. I was trying to look at racetronix's today I did not see any 36# do you mean 37#? Or could you post up a link. Please thanks in advance.
