i was curious as to when should someone put bigger injectors in, and what would happen if you put bigger injectors to a damn near stock ls motor? what would happen?

Without tuning, bigger injectors ruins your motor. You don't need bigger injectors with a near stock motor

^He is correct! My tuner had a customer with an LS2 GTO who put a supercharger on it. There was nothing in the kit warning him of the consequences of running larger injectors without tuning. He ran 60lb injectors for quite a while before having the car tuned. With no tune, the injectors actually washed out the rings. As soon as they entered boost, the oil dipstick shot out and hit the ceiling. Long story short, the customer's motor was shot. You won't need injectors until you do a cam swap. Always have the car tuned for bigger injectors. My tuner advised a friend of mine to get his car towed the 20 miles to the shop to avoid damage due to bigger untuned injectors.

With cam and bolt ons you will be close to maxing the stockers out. If you go with a bigger injector on a stock motor idle quality may suffer some but it will run fine. You cannot run the motor without the proper tuning for the injector.
