From what a guy on an EcoBoost forum said, the ST's CDFP is set at its maximum threshold just like the Mazda's is. These fuel pumps are set to push out around 1600psi under full boost (pretty nuts), and modification and tuning will require more, which puts the ST in the same modding situation as the Mazda.

I'd look into what's available for aftermarket. Sounds like with even a stage 1 tune on an intake you'll run into some moderate fuel starvation problems.

The Ford Pushes 2200 lbs and hasn't come close to being at it's limits yet. A guy on the Mazdaspeed forum is modding his ST with a big turbo and has hit 330 hp w/o a special tune. He thinks he can hit 400 on the stock internal fuel system....time will tell.
