Default When changing injector size

Do you have to have the computer or mass air recalibrated to make any changes in the injector size? I read it where some are using FORD injectors. What is the best for N/A 98 ?

You should tune the car for the new size injectors. On the flip side, what mods do you have to need bigger injectors?

I agree with new vetter in asking why you are contemplating this mod. Injectors only need to be upgraded if you are running a setup that renders the stockers inadequate and you won't reach that level until you add components that need significantly increase the fuel requirementssuch as a supercharger, turbo or aggressive head/cam setup. You'd need to initially scale the injector fuel rate (IFR) table in the PCM to compensate for the larger injectors. I did this swap a few months ago and posted a writeup about it.
