Fuel cut is a ECU limit to the airflow. It is a factory setup failsafe that stops the vehicle from continuing to boost, incase of a wastegate failure. Adding a fuel pump would not fix the ecu mass flow limit as you aren't changing the airflow number. The higher boost is causing you to hit it. Stick to 14psi to be safe.
Next round of mods for you:
-fuel pump
-possible injectors
-fuel controller/tuning device
-tune or a way to monitor a/f ratio
-the stock plugs are fine now, go a stage colder once you get the fueling mods situated.
