LS6 Injectors

I have a '99 C5. So after some research & purchasing some bolt-ons I decided to purchase 28.8lbs/s Injectors to accomodate the extra fuel needed as opposed to the stock 26lbs/s injectors. My question is : Do I need to do any programming changes or the size change is too small to warrant such measures ?

Just a guess that you will need to increase IFR values 5 or 10 %. I would not change anything until after scanning LTFTs.

offset is stock and the Flow rate has to be adjusted to get the ltft's back near non-positive.

I'd scan it and see what LTFTs do. Without program changes the Base PulseWidth will remain the same and therefore greater mass/volume of fuel will flow with the new injectors. PCM will pull fuel to correct - thus reducing LTFTs. Hope this helps some
