Welcome to the forum ! Outside of cold air intakes and exhausts there really isn't a whole lot to be done without a tune. Ford does offer performance tuning at some dealerships that won't completely destroy your warranty.

Welcome welcome. You're right about it being a great deal, had a guy in a GT350 having a hard time catching up on the track, and he swore I had cams. Put it in track mode and beat the stuffing out of it, you'd be surprised how much more is hidden in there. Not much else to do, as the Bullitt is pretty much the GT350 Intake Manifold and a Cold Air, and that's 480hp. Sticky tires also help, really wakes the thing up.
