I have a crate LS3 with the hot cam. Using an E38 with the 09 corvette LS3 tune. I just happen to also have a new LS7 intake and the tune for the 09 corvette LS7. I was going to build an LS7 but HP to HP the LS3/hot cam was cheaper. The injectors in both intakes are the exact same injector but some of the values in the tunes are different. The part number for the injector is 12576341. I am trying to figure out which values are the correct ones. One example of the difference is on the Injector flow rate vs. pressure delta table the ls3 starts at 23.6 to a max of 57.8, while the ls7 starts at 41.7 to a max of 52.5. Any help would be appreciated.
