I have a 2013 SHO with PP, I would hands down go with the unleashed tune, Torrie is the man. My warantee just ran out in Dec. and I had a KILLER tune in it with Meth right from 2 weeks after I owned it. You dont have to go that overboard, but you can feel VERY safe with Torrie. If I had to take it back for something, I would just return it to stock.
