2013 ram 1500 5.7 hemi. Just put in a new motor and am doing long tube headers, catless y pipe, and a CAI. I also purchased a diablo i3 tuner. My question is do I need a custom tune for this setup or can I run one of the preset tunes? Anyone running this setup have any input? If I do end up needing a custom tune will it hurt the motor if I run one of the preset tunes until I can get a custom tune?
