dont worry about the p1000 code it wont give the problem you have , initially it appeared that you had boost pressure related problems but from the code numbers they are not linked.
it would be worth ruling out a possible seizing vane unit in the turbo. very simple to test the turbo with electric actuator, lift the bonnet stand by the drivers door, start the car by putting your hand through drivers window aperture and at the same time peer through the gap beneath the bonnet, watch the arm/rod the actuator drives it should travel forward until the offset pivot on the actuator is approx at 1 o clock , turn off the engine and it should return the pivot to approx 9 o clock.
the vacume type you need two people, watch the rod that comes from the unit the small vac pipe goes to, when the car is started in should retract into the vac capsule approx 12 to 15 mm.
it may also be better to have the codes read with ford specific diagnostic equip.
