any advice gratefully received regarding my 07 reg duratec 225 focus st. it seems down on power?? as if the turbo is not working?? i took off the air intake pipe into the throttle body & there seemed to be loads of pressure there?? no faults present...??

 

Have the dealer or independent with the correct equipment read the engine and check the sensor values. It may be necessary to test drive with a scanner connected.
