    Lmm duramax. Egr removal, efi live, and wcfab y bridge kit

    I want to fully delete the egr on my lmm duramax. I've done research and would rather just remove it totally. What would be a good delete kit for me. Also would you guys recommend a y bridge? Also a little more knowledge on efi live would be great. The best setup? Best place to purchase it? Thanks.
