    Yes you'll have problems. There is NO point in changing injectors if you dont have to.

    If you get larger injectors without a tune. You will run really rich.

    So unless you are running out of injector. No reason to change.

    You have to get a tune with bigger injectors, otherwise you'll run real rich. There is no need or benefit of using bigger injectors, unless you have a big heads/cam, stroker, FI and actually need them.
