I found this:
Clean the hose mating surfaces to ensure the hoses will stay in place. Seat the hoses completely onto their mounting surfaces before tightening the clamps to 9 ft/lbs. Undamaged hoses may be reused, but they must be cleaned and inspected. If the inside of the hose is blue, it is recommended to apply a thin uniform coating of Motorcraft TA-31 RTV silicone to the mounting surface after cleaning. After reeassembling, allow the silicone to cure for three hours before driving the truck. Test drive the truck while monitoring the boost pressures, which should be 22-25 PSI. An overboost condition will cause the hose to blow off.

On 2004/05 trucks that exhibit the cold side hose/pipe blowing off at the intake manifold, replace the plastic tube with part #6C3Z-6C640-AA as in recall 05B29 (trucks built from 12-15-03 to 4-1-04), or repair as in TSB # 05-22-3 (trucks built from 4-1-05). Clean the intercooler and intake flange with brake parts cleaner. Seat the hose/pipe onto the intake manifold and torque the clamp to 9 ft/lbs (12 NM).

9 ft-lbs...? Sounds weak.
