Before spending money on different tuning for your (what I assume from your list of parts) 1995-1997 7.3L, run the tuning you have and see how it goes. The tuning for stock AA injectors and tuning for larger singles with stock nozzles will start out identical and most higher-horsepower calibrations for stock AA injectors "call for" more than what the stock injectors will provide anyway.
Stock and lower HP calibrations will run identically to what you had before and the higher HP calibrations will run stronger. I don't see a charge air cooler ("intercooler") in your list; stock injectors with additional fuel can get you into the danger zone of exhaust gas temperature under certain conditions and more fuel will only make it worse. I have two 1995s that would push almost 1200 degrees on a long climb with AAs and mild tuning. After CAC installs (from 1999 donors), 1000 is all either will ever hit regardless of load, ambient temp, or RPM.
