help with changing injectors

running aem v1 have the fuel map tuned pretty good running evo 560 injectors. i tried to install my RC PL4-750 injectors changed the fuel injectgor size and pressure and also changed the batt offset (not sure if they are the right settings but tied a couple) when tring to get the car to start i have to add a ton of fuel to get it to start and idle. any idea what i need to do to fix this?
