There may be some tuning changes that can help stay under that hard limit but likely you will need to go back to your larger pulley or upgrade to LT4 High pressure pump and injectors to raise that ceiling. Ted.

The cam lobe has to change to change the stroke of the pump to increase fuel delivery. And this would not solve the hard limit of the injectors. Ted.
