mondeo 54plate tdci holding back boost issue? am totally stuck
 

Right Ok hoping some on here can help. Got a euro 3 130tdci on a 54 plate. Had and injector pack In on me about 5 moths ago so fitted new one and coded it and been great until now. Another injector packed in on Friday there so got an other recon injector from same place put it in and coded it and ran fine or so a thought until a when to over take in 3rd gear pulled out foot down took of as normal until a hit 2200 rpm and the just seam to die out would go past 3000 rpm and boost dropped to 4psi dose this in every gear put foot down goes reads full boost 22psi then hit 2200 and it drops to 4-5 psi. Showing no fault codes and no lights. Any help would be great. Thanks
