  Can I run 50% over nozzles on stock injectors ?

  No, you cannot run 50% over nozzles on stock injectors. While the nozzle will physically bolt onto the injector body, the internal electronics and mechanics of a stock Bosch common-rail injector are not designed to handle that much fuel delivery.
