A lot of people think this is still the case with EFILive and are holding off using EFILive till the Switchable Tuning comes out. I am here to say, from a experienced user's standpoint of switches with Duramaxes, it is not needed. Handy? Sure. It has it's place. BUT YOU can have your cake and eat it too!! Provided you know what your doing, it IS possible hit the track and then the fields to tow your round bales of hay around without "de-tuning."
Same goes for if starts to sprinkle a little rain. You don't have to have a heart attack that your truck's gonna go careening sideways off the road because of the hot box tune you're running to support your higher hp truck. EFILive makes it possible to tune all that garbage out IF you know what you're doing or if you let one of the finer tuner's on here handle it for you and develop a good repore with them and learn.
