This, I got my SHO recently as well and haven't tuned yet but will be very soon. I would stress that any tune can possibly void the warranty. While flashing back to stock(along with changing the MAP if you go with the 3-bar) will lessen the chance, Ford can still tell the ECU was flashed. The odds of anyone going through the trouble is relatively low for most issues but catistrophic failure resulting in a large warranty repair cost can bring unwanted attention to anything Ford can use to void you. Just be aware and don't have things like tuner stickers or license plate frames on the car when you bring it in.Well, technically any mod can void your warranty. But a simple tune 3bar map will make you quite happy. And offer ease of going back to stock for dealer visits if you choose. Also definitely get a start on a good maintenance routine. Especially a trans fluid change and ptu fluid
