Question injector upgrade

My 99 expy has 113k miles, so I'm thinking of replacing injectors with a tune-up. If I upgrade from 19 to 24 psi injectors, will I need to change anything else at the same time? Thanks in advance for your expertise.

Yes, you will need either a custom chip or a new mass air flow meter that is calibrated for your vehicle and 24lb injectors.

If nothing else is changing why would you upgrade to 24lb injectors?

injector upgrade

I want to increase power, but, funds are limited. I plan to add intake mod such as k&n and bigger exhaust. I asked about the 24lb injectors as I've come across a very good deal on a new set of 24 lb'ers and was already thinking about replacing the originals due to some misfiring. I already planned to replace the plugs, and thought, hey.., maybe good to replace injectors at the same time to cut off future problems.
