    Have a new 2018 GT automatic, only mod I have is axle back exhaust and xpipe. I know custom tunes or a dyno is generally the way to go, my question is is the canned SCT tune for the 2018 really that bad? I did load it and the throttle response and shifting is way better over stock, however I'm kinda curious if they made any changes that can be be harmful long term to the vehicle.
