    nnbs intake and injector swap to lq4

    hey, im putting on a nnbs intake on my lq4. It has 12613411 injectors. How do i change this data to my lq4 computer? I found a ls3 to ls1 spreadsheet on here but the labels not match up to the 12613411 injectors. Does anyone have a spreadsheet that works?

    Also what do i have to change in the tune for the bigger throttle body?

    Some files the labels don't match 100% but you can still make it work. Plug in the GEN 4 style data the best you can and it will spit it out in the GEN 3 format.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.
