30# accel fuel injectors

How do i change this in tunercats for my 95 camaro the injector size. i just put in the 30# accell injectors the only thing i did with tunercats is change from 24 to 29.9 in the constant table is that all i do to set the bigger injector size or do i have to do something else

It depends. If the 30# accels are rated at the same psi as your stock injectors then you should be fine. If they're rated 30# at a lower psi you'll have to do some calculations.
