I have some Jegs exhaust cutouts for my 2012 Shelby GT500 and I was wondering if I need to get a tune from SCT or something like that in order for my car to run properly/safely. Can anyone help please! I'm asking this because I've heard all sorts of stuff from people "yes you need a tune", "no you don't need a tune". Either way I already have an SCT programmer so if it turns out I need a custom tune I'm halfway there but if I don't need to spend the money even better. It makes sense to me that I would need a tune because with cutouts there should be raw/unspent fuel coming through, anyway let me know your thoughts, thank you guys.
