injector question

[ranchhand99]

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?

[SCUFFY828]

yes they will, will work just fine

[ranchhand99]

thanks for the quick response. ive heard the 03 injectors are slightly larger so will i see a performance gain?

[SCUFFY828]

they are a larger cc injector ,how much gain would be the question, probably not very noticeable

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

yea if especially if you keep the edge on it....with custom tunes you would notice the biggest difference

you will see bigger gains swapping the HPOP and doing the IDM mod with them 140cc injectors...

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?
