I just bought a set of 8.1l truck injectors to get my duty cycle down. I currently am running up to 127%. I know my LTFT's are way off, and Im running pig ritch, but figure these will give more room to expand later anyway.

So isnt it just a plug and play swap, does anyone know the rating of these (I tried to search cause I know Ive seen it before, but couldnt find it) and or anything else I need to do teh swap? What do I need to change in the tune etc? Thanks

this may help, i know i saw it in this thread somewhere on how to program for them. I dont think its plug and play, I think you need to specify your injector size compared to stock. Dont quote me on this but, it was something to the effect that:

stock is 31lbs p/h (8.1l) and your replacing that with 43lb p/h which is a 28% increase over stock. So the table need to reflect that increase over stock. It was something to that effect, but i cant remember exactly, so please dont take this as scripture, i may be way off.

You'll need to get the IFR table change to reflect the correct settings of the 8.1 injectors. Other than that, they swap right over.
I just did mine about 2 weeks ago, my duty cycle wasn't quite as high as yours but it brought it down a good amount.

As far as the mechanical side its just plug and play the tuning side looks like it has already been covered.

I thought oyu were asking if they just plugged into the injector harness and all that and they didnt answer that, they answered about tuning it. So Matt, STFU a$$hole
