    Default LB7 to LLY Head and Injector Swap

    I have a 2004 Silverado 2500HD LB7

    Just swapped the cylinder heads with LLY Heads along with LLY Fuel Injectors

    Anyone have a base tune file to get the truck running they would share or know what I need to adjust in the LB7 tune to make it run with the new LLY Injectors?
