Its backing off to save the tranny, built into it with or without attitude, if you don't like it you need to either buy a box that doesn't back off the power and cooks your tranny or build your tranny up to take the power. With the attitude you can turn the defueling off which you cannot with just the juice to see how it acts but you most likely will put the tranny in limp mode on level five in 5th gear.....
