2004 Silverado, upgraded fuel system including boost reference fpr. Have all the injector data but have heard that you need to only use one column in the injector flow rate and the offsets and copy across the table. I’ve seen 0 kpa and 80kpa. I have them set at 80 and I’ve added almost 70% more fuel and can not get the engine to richen up to stoich.
