injector question

Im thinking my injectors might be bad and I have a set of injectors out of an 03 7.3. Im wondering if these injectors will work in my early 99?

They are only a tad bit bigger, you might see a small improvement but don't expect much.

Wait, I thought that was why you needed custom tuning to run single shot injectors. How would split shots run with a single shot ecu or program?

i dont see where any one said any thing about SS....all super duty's have splits..early 99 has 120-130 cc 99.5-03 have 140cc..all split shots...

you can use SS on split shot tuning..it will idle ruff..but it will run...

That's what I'm getting at. Won't it act funny and hicup or do something odd?
