Ze - yes, the boost box is off the truck ready to ship.
I've received several PMs regarding the boost box and springs. Here's some additional information.
Springs - The 754s are for the rear of the 110 only. The 110 rear springs are larger in diameter then the front and 90 rear springs. Therefore, only 2 springs are available, not 4. I would recommend doing a search on OME springs to gather additional data like spring rate, etc.
Boost Box - only applicable for the TD5. Allows you to increase boost pressure without the ECU going into limp mode or reduce fueling. Again, any interested I would recommend reading TD5Alive or AliveTuning's website. They provide a good write-up.
