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?

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...

some guy's have run SS injectors with a stock PCM till they get a tuner..it idles ruff but smooth out under throttle.. the full power of the SS are not felt all that much till you get the tunes to match..
