i think helping it breath better, exhaust, maybe ignition. depending on the stock turbo maybe change it out with one that might be able to do a little more with in the same range as the stock turbo.
i dont see why ford or any other company would produce a car that is already pushing its limits unless it was just something like fuel managment or a gasket. they would know that the group of people the car is being sold to would only want more from it and ford could only profit from it by producing their own upgrades for it.
just takes time for parts to come out.
