Fuel injectors have an optimal duty cycle. Once you past the maximum duty cycle it is very likely they go static causing instability and lean conditions in your motor. There are some good videos on youtube showing what happens when you go too high in pressure and the Injectors pretty much shut down. 100 psi is insane on stock injectors!
