Your computer is basing stock fuel calcs on 58psi. Your injector data sheet should say what rail pressure they were rated on. Increasing rail pressure that much means changing the working flow rate of the injectors, since injector flow is volume@pressure. Your 80lb injector could be more like 110lb with a ~30% increase in rail pressure...let alone whatever the boost ref commands. It'll be a tw@t to idle and part throttle it.

Injector Dynamics could get you set up, but that means $$$$

Otherwise you can buy yourself some margin and run a secondary fueling/meth system.
