I guess it depends on how much HP the car is making with the 100 shot activated.
The LS3 uses the same injectors as the 505 Net HP LS7 engine (42 Lb/Hr @ 58 PSI)
A dyno pull with a wide band could tell you if it is leaning out any when the 100 shot is activated at WOT.

If you don't want to spend big bucks on injectors, just get a set of OEM LS9 injectors (they are 52 Lb / Hr @ 58 PSI)
It's the next step up from your stock LS3 injectors.
However, when you make an injector change, you most definitely need to get the car dyno tuned to run on the new injectors ... If not, it will run like crap.

You’re going to be very close or at the limit of your fuel system with a cam and nitrous, even with just a 100 hp shot, and the injectors will probably be at or beyond their limit with a 100 hp dry shot. If it’s wet, it doesn’t matter what injectors you’re running.
You might get away with it with a small cam, but it’s not worth it to risk grenading your motor, IMV.
The cheapest solution would be to get a Racetronix fuel pump harness with the aux fuel pump booster connector kit and a BAP and wire the BAP to switch on when you arm or activate the nitrous.

I drive over to Pompano Beach (just north of Fort Lauderdale) and have Howard Tanner at Redline Motorsports do the dyno tuning .... Excellent shop that specializes in later model GM
